#Coreboot build helper I wrote this to assist in building a custom coreboot rom for Lenovo x230.

Note: I haven't used this in a while. For example, my latest Coreboot builds, I no longer use the zerocat or other custom configs.

What it do

So far, it will:

1. Removes old coreboot roms
2. Builds new coreboot roms
3. Adds custom files
   • zerocat.cfg
   • Moves secondary payloads
   • Adds seabios payload
   • Adds background image(s)
4. Tweak parameters
   • gfx_uma_size=224M
   • wwan=Disable
   • bluetooth=Disable
5. Split 12M rom into 8M(Bottom) and 4M(Top) files
