U-Boot standard boot methods (bootmeth)
======================================
This provides methods (called bootmeths) for locating bootflows on a boot
device (bootdev). These are normally created as children of the bootstd device.
Required properties:
compatible:
"u-boot,distro-syslinux" - distro boot from a block device
"u-boot,distro-pxe" - distro boot from a network device
"u-boot,distro-efi" - EFI boot from an .efi file
"u-boot,efi-bootmgr" - EFI boot using boot manager (bootmgr)
Example:
bootstd {
compatible = "u-boot,boot-std";
filename-prefixes = "/", "/boot/";
bootdev-order = "mmc2", "mmc1";
syslinux {
compatible = "u-boot,distro-syslinux";
};
efi {
compatible = "u-boot,distro-efi";
};
};
