From 081dfcf783c80a8abf717df984c94970d128b98a Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Jan 2022 03:51:16 -0700 Subject: x86: efi: Set the correct link flags for the 64-bit EFI app At present some 32-bit settings are used with the 64-bit app. Fix this by separating out the two cases. Be careful not to break the 64-bit payload, which needs to build a 64-bit EFI stub with a 32-bit U-Boot.
