Subject: s5pc110: fb: moved framebuffer region to reserved one.
X-Git-Tag: JC13_20100322~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c5ae09fa97700e9e5858db9c87fdddec9832bc93;p=kernel%2Fu-boot.git

s5pc110: fb: moved framebuffer region to reserved one.

this region reserved wouldn't be rewrited by kernel.
so after hibernation is completed it can avoid screen filled by garbages.
