Hi, Marczak

I think, this patch can make unalgined access.

(maybe.. this code)
if (vid->vl_bpix == 4)
        vid->logo_addr = (ulong)tizen_hd_logo_16bpp;
else
        vid->logo_addr = (ulong)tizen_hd_logo;

Compiled using arm-linux-gnueabi (4.6.3 version) and
When I tested using TRTAS2 board,

I can face data abort error message like this,

//////
data abort

     MAYBE you should read doc/README.arm-unaligned-accesses

Actually I used GCC 4.5. Linaro Gcc versions >= 4.6 has unaligned acces enabled by default. Maybe flag -mno-unaligned-access will avoid this. I will check this issue.

Regards.
