   doc/efi: add load file 2 protocol to HTML documentation (2020-02-28

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.
