From: InKi Dae <inki.dae@xxxxxxxxxxx> it has been working fine at 16bpp but in case of pixel format more then 24bpp it would occur distortedness situation on that mode. so this patch set the word swap control bit of WINCONx to 1 as default value. but it should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers is enabled. this issue would be solved with local path feature soon.
