Date: Tue, 29 Dec 2015 12:09:19 +0800	[thread overview]
Message-ID: <1451362159-27910-1-git-send-email-sdliyong@gmail.com> (raw)

Based on the below
commit ae3c99a26c60 ("ARM: 7806/1: allow DEBUG_UNCOMPRESS for Tegra"),
change the .data section to .text section,
to enable DEBUG_UNCOMPRESS for OMAP2+ platforms
Tested okay using BeagleBone Black
