U-Boot standard boot device (bootstd)
=====================================
This is the controlling device for U-Boot standard boot, providing a way to
boot operating systems in a way that can be controlled by distros.
Required properties:
compatible: "u-boot,boot-std"
Optional properties:
filename-prefixes:
List of strings, each a directory to search for bootflow files
bootdev-order:
List of bootdevs to check for bootflows, each a bootdev label (the media
uclass followed by the numeric sequence number of the media device)
Example:
bootstd {
compatible = "u-boot,boot-std";
filename-prefixes = "/", "/boot/";
bootdev-order = "mmc2", "mmc1";
};
