Welcome to PC Engines and the ALIX 1C!
This is a geode LX board. There are timing settings that are not right yet, we are still trying to get our board to boot Linux :-) Signed-off-by: Ronald G. Minnich <rminnich@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2765 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

1. If we are using the auto.inc ROMCC way, the stack is going to be re-setup in the code following this code.

Just wbinvd the stack to clear the cache tags. We don't care where the stack used to be.
|

2. This file is built as a normal .c -> .o and linked in etc. The stack might be used to return etc.
|
||||
That means we care about what is in the stack. If we are smart we set the CAR stack to the same location
|
||||
as the rest of LinuxBIOS. If that is the case we can just do a wbinvd. The stack will be written into real
|
||||
RAM that is now setup and we continue like nothing happened. If the stack is located somewhere other than
|
||||
where LB would like it, you need to write some code to do a copy from cache to RAM
