[LinuxBIOS] LInuxBIOSv3 - Reset and CAR code

[Juergen Beisert]

Hi,

currently I'm trying to understand how it works in assembly until C starts. 
Could we divide the stage0_i586.S file into its three parts? Resetvector, 
Jump to protected mode and the CAR code? Maybe it would be easier to 
understand and to maintain.
With my GeodeGX1 systems I cannot use the mtrr registers to get some memory 
from the cache. To replace it a complete new file would be required. Maybe it 
would be better to support different methods how to get CAR and link them on 
demand?
