Don't worry about it I'm a little busy too. :)

My suggestion is to remove completely the logo support and rewrite the
function:

   int lcd_display_bitmap(ulong bmp_image, int x, int y)

in order to support, in a easy configurable way, all bpp LCD
resolutions.

On my side I can write and test the code for 16bpp LCD on a PXA2xx but
I need help and support for other resolutions and CPUs! It could be
acceptable to write a first version of such function for my hardware
and then adding the other support even if it could break current board
logo/splash support?

Ciao,

Rodolfo
