From abc3b43996198012498abe5777cfeedde4538a90 Mon Sep 17 00:00:00 2001

Subject: [PATCH] workaround for scatter gather flag check for corstone1000
This workaround passes 1 as scatter_gather_list value to pass the NULL checks
for scatter_gather_list while CAPSULE_FLAGS_PERSIST_ACROSS_RESET flag is set
(which is introduced lately to align with UEFI specs). Since these flag checks
are not implemented in u-boot properly and corstone1000 does not support
scatter_gather_list during capsule update, this patch will skip the check only
for on-disk capsule update.
Signed-off-by: Emekcan Aras <emekcan.aras@arm.com>
Upstream-Status: Inappropriate [Redesign of Capsule update interface is required]
