fbcon: logo: allow easy integration of a custom Linux boot logo
This patch allows for easy integration of a custom Linux boot logo to
replace the Tux' being shown by default.
Use gimp or the like to create a raw PPM in your desired resolution.
Reduce the number of colours in the image to 224:
user@host:~$ ppmquant 224 Toradex-640x480.ppm > \
Toradex-640x480-224.ppm
ppmquant: making histogram...
ppmquant: 370 colors found
ppmquant: choosing 224 colors...
ppmquant: mapping image to new colors...
Convert it from raw PPM to ASCII format:
user@host:~$ pnmnoraw Toradex-640x480-224.ppm > \
Toradex-640x480-ascii-224.ppm
Copy it into the Linux sources:
cp Toradex-640x480-ascii-224.ppm linux-toradex/drivers/video/logo/\
logo_custom_clut224.ppm
Activate exclusively custom Linux logo in the kernel configuration:
Device Drivers -> Graphics support -> Bootup logo ->
Custom 224-color Linux logo
And re-compile the kernel.
