[PATCH v3 22/31] bootstd: Add an implementation of EFI boot

[Michael Walle]

> Add a bootmeth driver which handles EFI boot, using EFI_LOADER.

FWIW, the distro boot will also load the device tree from the installer
medium for example. The filename is fetched from fdtfile. This is missing
here, thus for my board, this cannot be a replacement for distro boot;
which is the ultimate goal here, no?
