Pull request for UEFI sub-system for efi-2020-04-rc4 (2)
In Linux next-20200228 patches have been merged to load an initial ramdisk
using an EFI_LOAD_FILE2_PROTOCOL provided by the firmware. See commit
ec93fc371f01 ("efi/libstub: Add support for loading the initrd from a
device path"). The idea behind it is that the firmware should be
responsible for validating the initrd in a secure boot setup.
This pull-request comprises a patch series which let's U-Boot provide an
initial implementation of the EFI_LOAD_FILE2_PROTOCOL providing the initrd.
