Thanks a lot! Here's a quick review:

I think the full name for this specific board is "PCISA-LX-R11",
correct? If so, please use that everywhere (directory names, strings,
variable names, comments). "PCISA-LX" seems to be the general name for a
whole family of boards.

So the directory name should probably be 'pcisa-lx-r11'.

Either the code you grabbed from the DB800 target is trivial (then drop
this line completely), or it is not (then retain the Copyright lines from
the respective DB800 file please).

In this case the file is a plain copy of the DB800 one, with small fixes
in the #defines at the beginning, so please keep the original
copyright/license header and drop the "Borrowed from amd/db800".

As this function is exactly the same for this board (and DB800), is it
possible that it's not really board-specific anyway? If so, it should
be moved to a global location in the chipset code.

I think you can/should just use DIMM0 / DIMM1 here.

You have

default HAVE_OPTION_TABLE = 0
  default USE_OPTION_TABLE = 0

in Options.lb so this file is never used and we should drop it (or
enable it's usage, if it's tested and works).

Also, it should have a license header.

Hm, does this mean it's not used at all? If so, drop the file
completely. You'll have to fix up the Config.lb file a bit so
it still compiles if you do that (grep for "failover").

Nope, this one is actually quite different from the DB800 file and
produced by you manually, I assume? If so, drop the "Borrowed from
amd/db800".

?

Are you trying to make this table compatible with two different boards?
If yes, does the rest of the code work fine with both of them?

Yuck. Again a huge pile of code which can't be _that_ board-specific if
it works for at least two boards (this one and DB800). Should be moved elsewhere
IMO (but that's probably for an extra patch).

This is a change from the DB800 target:

-default CONFIG_UDELAY_TSC=1
 -default CONFIG_TSC_X86RDTSC_CALIBRATE_WITH_TIMER2=1
 +default CONFIG_UDELAY_IO=1

No TSC or TIMER2 on Geode boards?

Keep this "./linuxbios.rom" please, we do that will almost all boards
and it's a good thing IMO.

HTH, Uwe.
