Hi all,

I'm porting BSP code from v2.6.36 to v3.10 kernel. It's ARMv7 processor.

But decompressor doesn't work. With a lot of debug, I finally find
below 2 commits related.
Kernel uncompress OK with these commits reverted.

dbece45: ARM: 7501/1: decompressor: reset ttbcr for VMSA ARMv7 cores
(Introduced in v3.6-rc6)

5010192: ARM: 7583/1: decompressor: Enable unaligned memory access for
v6 and above
(Introduced in v3.7-rc8)

Any hint to fix it?

Thanks,
Lin Ming
