From c8e4284acbdddd5afbef49c100e6aba44aba849c Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 1 Mar 2013 03:22:22 -0800 Subject: [PATCH] libpayload: Turn on thumb interworking in libpayload. Things work better with it turned on, and the overhead should be negligable. Built and booted into depthcharge on Snow. Verified that calling between various bits of thumb and ARM code worked correctly. Change-Id: I08d1006e113d2cca08634bf19240aca138a449d9 Signed-off-by: Gabe Black Signed-off-by: Ronald G.
