This patchset will build 64-bit U-Boot as a Slim Bootloader payload and introduce a new X86_RUN_64BIT_ONLY to build pure 64-bit U-Boot binary without SPL. In addition, this supports 64-bit kernel booting from 64-bit U-Boot.

One little thing that I noticed...your instructions show copying u-boot-dtb.bin into the slimbootloader directory. This is the same as u-boot.bin and I suggest you use that name instead. When I tried to, I got an error.
