How to display a full resolution Linux boot logo

When trying to use your own Linux boot logo (instead of Tux penguin splash) according to Digi ESP instructions 9.14.2.1 to change logo_custom_clut224.ppm, you will notice that higher resolution logos will not be displayed.

In order allow higher or full resolution Linux boot logos, please patch
/usr/local/DigiEL-5.8/kernel/linux-2.6.35/drivers/video/mxc/mxc_ipuv3_fb.c
