Thanks, I didn't know that.
I will update my patch and send a new version.

Not sure if raw_data_format_adjust() has a way of knowing if it's 24bpp 
or 32bpp. I'll look into it again.

Doesn't make too much of a difference if you use LZMA. (coreboot 
currently only offers adding an uncompressed BMP in its configuration, 
but it is easily added by hand with cbfstool and works fine with 
compression.)
