From 96a8d409a75af99ac7a9a9ba707d544f9cf44fc0 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Aug 2015 12:33:56 -0600 Subject: efi: Add 64-bit payload support Most EFI implementations use 64-bit. Add a way to build U-Boot as a 64-bit EFI payload. The payload unpacks a (32-bit) U-Boot and starts it. This can be enabled for x86 boards at present.
