From 65e4c0b168651285adeab66f32f3a14668f3e4bd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 25 Sep 2016 15:27:35 -0600 Subject: x86: efi: Add EFI loader support for x86 Add the required pieces to support the EFI loader on x86. Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application is supported. If a 64-bit kernel must be booted, U-Boot supports this directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a payload for both 32-bit and 64-bit EFI.
