booting fails on FAM10 machine

[Maximilian Thuermer]

Hi all,

I did a fresh svn co the other day and tried building and
running a Tyan S2912_fam10 system. With older sources
(rev 4729) everything worked just fine, with the newest checkout
the booting process stops at setting MTRR registers or a little
later (depending on the compiler used: 3.4.6 builds faster code
and gets further than 4.3.3, both Ubuntu fashion).
I tried tracking down the problem and it appeared to me as if
the switch from CONFIG_LB_MEM_TOPK to CONFIG_RAMTOP
must have something to do with this though I couldnt find an
error when comparing all the files affected by this switch.
Attached are the last lines of the debug printout.
Does anyone have an idea, where this error might come from
or if there are any unintended side effects associated with this change?

Thanks in advance,

Maximilian

It's possible.  Could you try Rev 4787 & 4788 to make sure, then send me the
logs from both?  I'm also interested in the coreboot_ram.map files.

There shouldn't have been any.  Hopefully everywhere it was (TOPK) it is now
(RAMTOP >> 10) and everywhere it was (TOPK<<10) it is (RAMTOP).

Thanks for helping track it down.
