The argument to reset_cpu() is _not_ actually passed from the `reset` command, but is set to 0 in all call-sites (in this specific case, see arch/arm/lib/reset.c). Thus, performing different kinds of resets based on its value will not work as expected. 2. Contrary to its documentation, the passed argument is not interpreted, but a static `L3_RESET` define is used. The other comment properly notes that this will always perform a L3 reset, though. 3. The "parsing" of the static `L3_RESET` value is not even using the upper and lower nibble as stated in the comment, but uses the last two decimal digits of the value. This is currently one of the only implementations left in U-Boot, which make "use" of the value passed to reset_cpu(). As this is done under false assumption (the value does not have any meaning anymore), it makes sense to bring it into line with the rest and start ignoring the parameter. This is a preparation for removal of the reset_cpu() parameter across the entire tree in a later patch.

This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead.

When MMU is activated in pre-reloc stage; only the beginning of DDR is marked executable. This patch avoids access issue when DACR is correctly managed.

But the format used hexdump by default differs from that shown by U-Boot. Add a note about how to make them the same. (For large dumps, writing the data to the network with tftpput, or to a USB stick with ext4save is easiest.)

Update the comment for os_free() to indicate that NULL is a valid parameter value.

Rename all the TPMv1 functions so they are called from the API. Update the TPMv1 functions so that they are called from the API. Change existing users to use the tpm1_ prefix so they don't need to go through the API, which might introduce uncertainty.

This makes it hard to test changing the flags since we need to be aware of the internal workings of the driver. The feature is designed to aid testing. Split this feature out into a separate sandbox-specific flag, so that the flags can change unimpeded. This will make it easier to allow updating the flags in a future patch.

Add a function for this. Update dm_gpio_set_dir_flags() to make use of this. Also update dm_gpio_set_value() to use this also, since this allows the open-drain / open-source features to be implemented directly in the driver, rather than using the uclass workaround. Update the sandbox tests accordingly. This involves a lot of changes to dm_test_gpio_opendrain_opensource() since we no-longer have the direciion being reported differently depending on the open drain/open source flags. Also update the STM32 drivers to let the uclass handle the active low/high logic. Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

Add an implementation of this. This involves updating the sandbox GPIO driver to model external and (weaker) internal pull resistors. The get_value() method now takes account of what is driving a pin: sandbox: GPIOD_EXT_DRIVEN - in which case GPIO_EXT_HIGH provides the value outside source - in which case GPIO_EXT_PULL_UP/DOWN indicates the external state and we work the final state using those flags and the internal GPIOD_PULL_UP/DOWN flags Of course the outside source does not really exist in sandbox. We are just modelling it for test purpose.

However, this struct can be empty if there are no actual devicetree properties provided. The upshot of empty platform data is that it will end up as a zero-size member in the BSS section, which is fine. But if the driver specifies plat_auto then it expects the correct amount of space to be allocated. At present this does not happen, since device_bind() assumes that the platform-data size will always be >0. As a result we end up not allocating the space and just use the BSS region, overwriting whatever other contents are present. Fix this by removing the condition that platform data be non-empty, always allocating space if requested. This fixes a strange bug that has been lurking since of-platdata was implemented. It has likely never been noticed since devices normally have at least some devicetree properties, BSS is seldom used on SPL, the dtv structs are normally at the end of bss and the overwriting only happens if a driver changes its platform data. It was discovered using sandbox_spl, which exercises more features than a normal board might, and the critical global_data variable 'gd' happened to be at the end of BSS.

We don't really need to have a separate test structure for the driver model tests and it makes it harder to write a test if you have to think about which type of test it is. Subsume the fields from struct dm_test_state into struct unit_test_state and delete the former.

This makes it hard to enumerate all the available tests without knowing the suites that each one is in. Place all tests together in a single contiguous list by giving them common prefix not used elsewhere in U-Boot. This makes it possible to find the start and end of all tests.

It is confusing to use a similar name for something that is not actually related. For the alignment code, ALIGN() is used instead of open-coded alignment.

They support both sandbox and +real hardware. They typically do not require building test code into U-Boot +itself. They are fairly slow to run, due to the command-line interface and there +being two separate processes. Python tests are fairly easy to write. They can +be a little tricky to debug sometimes due to the voluminous output of pytest. + +C tests are written directly in U-Boot. While they can be used on boards, they +are more commonly used with sandbox, as they obviously add to U-Boot code size. +C tests are easy to write so long as the required facilities exist. Where they +do not it can involve refactoring or adding new features to sandbox. They are +fast to run and easy to debug. + +Regardless of which test type is used, all tests are collected and run by the +pytest framework, so there is typically no need to run them separately. This +means that C tests can be used when it makes sense, and Python tests when it +doesn't. + + +This table shows how to decide whether to write a C or Python test: + +===================== =========================== ============================= +Attribute C test Python test +===================== =========================== ============================= +Fast to run?

This +allows fast testing, easy development and allows contributors to make changes +without needing dozens of boards to test with. + +When a test requires setup or interaction with the running host (such as to +generate images and then running U-Boot to check that they can be loaded), or +cannot be run on sandbox, Python tests should be used. These should typically +NOT rely on running with sandbox, but instead should function correctly on any +board supported by U-Boot. + + +How slow are Python tests? +-------------------------- + +Under the hood, when running on sandbox, Python tests work by starting a sandbox +test and connecting to it via a pipe. Each interaction with the U-Boot process +requires at least a context switch to handle the pipe interaction. The test +sends a command to U-Boot, which then reacts and shows some output, then the +test sees that and continues. Of course on real hardware, communications delays +(e.g. with a serial console) make this slower. + +For comparison, consider a test that checks the 'md' (memory dump). All times +below are approximate, as measured on an AMD 2950X system. Here is is the test +in Python:: + + @pytest.mark.buildconfigspec('cmd_memory') + def test_md(u_boot_console): + """Test that md reads memory as expected, and that memory can be modified + using the mw command.""" + + ram_base = u_boot_utils.find_ram_base(u_boot_console) + addr = '%08x' % ram_base + val = 'a5f09876' + expected_response = addr + ': ' + val + u_boot_console.run_command('mw ' + addr + ' 0 10') + response = u_boot_console.run_command('md ' + addr + ' 10') + assert(not (expected_response in response)) + u_boot_console.run_command('mw ' + addr + ' ' + val) + response = u_boot_console.run_command('md ' + addr + ' 10') + assert(expected_response in response) + +This runs a few commands and checks the output. Note that it runs a command, +waits for the response and then checks it agains what is expected. If run by +itself it takes around 800ms, including test collection. For 1000 runs it takes +19 seconds, or 19ms per run. Of course 1000 runs it not that useful since we +only want to run it once. + +There is no exactly equivalent C test, but here is a similar one that tests 'ms' +(memory search):: + + /* Test 'ms' command with bytes */ + static int mem_test_ms_b(struct unit_test_state *uts) + { + u8 *buf; + + buf = map_sysmem(0, BUF_SIZE + 1); + memset(buf, '\0', BUF_SIZE); + buf[0x0] = 0x12; + buf[0x31] = 0x12; + buf[0xff] = 0x12; + buf[0x100] = 0x12; + ut_assertok(console_record_reset_enable()); + run_command("ms.b 1 ff 12", 0); + ut_assert_nextline("00000030: 00 12 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................"); + ut_assert_nextline("--"); + ut_assert_nextline("000000f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 12 ................"); + ut_assert_nextline("2 matches"); + ut_assert_console_end(); + + ut_asserteq(2, env_get_hex("memmatches", 0)); + ut_asserteq(0xff, env_get_hex("memaddr", 0)); + ut_asserteq(0xfe, env_get_hex("mempos", 0)); + + unmap_sysmem(buf); + + return 0; + } + MEM_TEST(mem_test_ms_b, UT_TESTF_CONSOLE_REC); + +This runs the command directly in U-Boot, then checks the console output, also +directly in U-Boot. If run by itself this takes 100ms. For 1000 runs it takes +660ms, or 0.66ms per run. + +So overall running a C test is perhaps 8 times faster individually and the +interactions are perhaps 25 times faster. + +It should also be noted that the C test is fairly easy to debug. You can set a +breakpoint on do_mem_search(), which is what implements the 'ms' command, +single step to see what might be wrong, etc. That is also possible with the +pytest, but requires two terminals and --gdbserver. + + +Why does speed matter? +---------------------- + +Many development activities rely on running tests: + + - 'git bisect run make qcheck' can be used to find a failing commit + - test-driven development relies on quick iteration of build/test + - U-Boot's continuous integration (CI) systems make use of tests. Running + all sandbox tests typically takes 90 seconds and running each qemu test + takes about 30 seconds. This is currently dwarfed by the time taken to + build all boards + +As U-Boot continues to grow its feature set, fast and reliable tests are a +critical factor factor in developer productivity and happiness. + + +Writing C tests +--------------- + +C tests are arranged into suites which are typically executed by the 'ut' +command. Each suite is in its own file. This section describes how to accomplish +some common test tasks. + +(there are also UEFI C tests in lib/efi_selftest/ not considered here.) + +Add a new driver model test +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Use this when adding a test for a new or existing uclass, adding new operations +or features to a uclass, adding new ofnode or dev_read_() functions, or anything +else related to driver model. + +Find a suitable place for your test, perhaps near other test functions in +existing code, or in a new file. Each uclass should have its own test file. + +Declare the test with:: + + /* Test that ... */ + static int dm_test_uclassname_what(struct unit_test_state *uts) + { + /* test code here */ + + return 0; + } + DM_TEST(dm_test_uclassname_what, UT_TESTF_SCAN_FDT); + +Replace 'uclassname' with the name of your uclass, if applicable. Replace 'what' +with what you are testing. + +The flags for DM_TEST() are defined in test/test.h and you typically want +UT_TESTF_SCAN_FDT so that the devicetree is scanned and all devices are bound +and ready for use. The DM_TEST macro adds UT_TESTF_DM automatically so that +the test runner knows it is a driver model test. + +Driver model tests are special in that the entire driver model state is +recreated anew for each test. This ensures that if a previous test deletes a +device, for example, it does not affect subsequent tests. Driver model tests +also run both with livetree and flattree, to ensure that both devicetree +implementations work as expected. + +Example commit: c48cb7ebfb4 ("sandbox: add ADC unit tests") [1] + +[1] https://gitlab.denx.de/u-boot/u-boot/-/commit/c48cb7ebfb4 + + +Add a C test to an existing suite +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Use this when you are adding to or modifying an existing feature outside driver +model.

For example:: + + #include + #include + #include + #include + #include + + /* Declare a new wibble test */ + #define WIBBLE_TEST(_name, _flags) UNIT_TEST(_name, _flags, wibble_test) + + /* Tetss go here */ + + /* At the bottom of the file: */ + + int do_ut_wibble(struct cmd_tbl *cmdtp, int flag, int argc, char *const argv[]) + { + struct unit_test *tests = UNIT_TEST_SUITE_START(wibble_test); + const int n_ents = UNIT_TEST_SUITE_COUNT(wibble_test); + + return cmd_ut_category("cmd_wibble", "wibble_test_", tests, n_ents, argc, argv); + } + +Then add new tests to it as above. + +Register this new suite in test/cmd_ut.c by adding to cmd_ut_sub[]:: + + /* Within cmd_ut_sub[]... */ + + U_BOOT_CMD_MKENT(wibble, CONFIG_SYS_MAXARGS, 1, do_ut_wibble, "", ""), + +and adding new help to ut_help_text[]:: + + "ut wibble - Test the wibble feature\n" + +If your feature is conditional on a particular Kconfig, then you can use #ifdef +to control that. + +Finally, add the test to the build by adding to the Makefile in the same +directory:: + + obj-$(CONFIG_$(SPL_)CMDLINE) += wibble.o + +Note that CMDLINE is never enabled in SPL, so this test will only be present in +U-Boot proper.

Typically this is automatic, since pytest +scans the U-Boot executable for available tests to run. So long as you have a +'ut' subcommand for your test suite, it will run. The same applies for driver +model tests since they use the 'ut dm' subcommand. + +See test/py/tests/test_ut.py for how unit tests are run. + + +Add a C test for SPL +~~~~~~~~~~~~~~~~~~~~ + +Note: C tests are only available for sandbox_spl at present. There is currently +no mechanism in other boards to existing SPL tests even if they are built into +the image. + +SPL tests cannot be run from the 'ut' command since there are no commands +available in SPL. Instead, sandbox (only) calls ut_run_list() on start-up, when +the -u flag is given. This runs the available unit tests, no matter what suite +they are in. + +To create a new SPL test, follow the same rules as above, either adding to an +existing suite or creating a new one. + +An example SPL test is spl_test_load(). + + +Writing Python tests +-------------------- + +See :doc:`py_testing` for brief notes how to write Python tests.

All the information flowing on buses (ie I2C) between the processor and the secure element must be encrypted. Secure elements are pre-provisioned with a set of keys known to the user so that the secure channel protocol (encryption) can be enforced on the first boot. This situation is however unsafe since the keys are publically available. For example, in the case of the NXP SE050, these keys would be available in the OP-TEE source tree [2] and of course in the documentation corresponding to the part. To address that, users are required to rotate/provision those keys (ie, generate new keys and write them in the secure element's persistent memory).

This information does not change across tests, so we can save time by remembering it. Add a way to set up this information and use it for each test, taking a copy first, so as not to mess up the original. This reduces the run time from about 1.6 seconds to 1.5 seconds on my machine. For code coverage (which cannot run in parallel), it reduces from 33 seconds to 5.

In order to generate build-time devices, dtoc needs to generate code that declares the data contained in those structs. This generated code must include the relevant header file, to avoid a build error. We need a way for dtoc to scan header files for struct definitions. Then, when it wants to generate code that uses a struct, it can make sure it includes the correct header file, first. Add a parser for struct information, similar to drivers.

The latter does not use dtoc. In some rare cases different drivers are used for two phases. For example, in TPL it may not be necessary to use the full PCI subsystem, so a simple driver can be used instead. This works in the build system simply by compiling in one driver or the other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has no way of knowing which code is compiled in for which phase, since it does not inspect Makefiles or dependency graphs. So to make this work for dtoc, we need to be able to explicitly mark drivers with their phase. This is done by adding an empty macro to the driver. Add support for this in dtoc.

In some cases, enums are used in drivers, typically with the .data field of struct udevice_id. Since dtoc does not support searching for these, add a way to tell dtoc which header to use.

This is determined by the drivers that use them. Check all the used drivers and build a list of 'valid' uclasses. Also add references to the uclasses so we can generate C code that uses them. Attach a uclass to each valid driver. For the tests, now that we have uclasses we must create an explicit test for the case where a node does not have one. This should only happen if the source code does not build, or the source-code scanning fails to find it.

17 00:00:00 2001 From: Dario Binacchi Date: Tue, 16 Mar 2021 21:51:44 +0100 Subject: [PATCH 174/357] bus: ti-sysc: change in a normal driver The module defines a duplicate uclass driver for UCLASS_SIMPLE_BUS, but it is not allowed. This breaks of-platdata and makes the result non-deterministic. The driver does not need to be an uclass driver, so lets remove it. I had turned it into an uclass driver because I thought wrongly it had to call the dm_scan_fdt_dev routine to work properly, but some tests on the board have shown otherwise.

This patch fixes this by using r6 instead of r4 in the lowlevel_init function. Discovered and the fix was tested on a AT91SAM9261 based board.

Although we correctly return various EFI exit codes depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the kernel loader, only falls back to the cmdline interpreted initrd if the protocol is not installed. This creates a problem for EFI installers, since they won't be able to load their own initrd and continue the installation. It also makes the feature hard to use, since we can either have a single initrd or we have to recompile u-boot if the filename changes. So let's introduce a different logic that will decouple the initrd path from the config option we currently have. When defining a UEFI BootXXXX we can use the filepathlist and store a file path pointing to our initrd. Specifically the EFI spec describes: "The first element of the array is a device path that describes the device and location of the Image for this load option. Other device paths may optionally exist in the FilePathList, but their usage is OSV specific" When the EFI application is launched through the bootmgr, we'll try to interpret the extra device path. If that points to a file that exists on our disk, we'll now install the load_file2 and the efi-stub will be able to use it. This opens up another path using U-Boot and defines a new boot flow. A user will be able to control the kernel/initrd pairs without explicit cmdline args or GRUB.
