[LinuxBIOS] Geode LX support

[Indrek Kruusa]

Could it be that setup for one LX board (amd/norwitch) does something very 
special that prevents this LB ROM to run (to some extent) on another LX board 
(artecgroup/dbe61)? It stops at postcode 0x10 (Entry into protected mode). I 
suppose that whatever LX target rom should be able to reach at least the 
pll_reset() on any another LX board without much problem.

thanks,
Indrek

Indrek,

The only thing I could think of is that new LX code uses CAR so if you 
were still trying to use romcc you would run into problems right away.
Is the problem at the first 0x10 or does it actually do the pll_reset() 
and stop on the second time around? Can you get serial output?

Marc's code works really well on at least 2 boards, it works fine on
the digital logic card.

thanks

are you working from the LB tree or your own tree?
