acpi_tables.c into the southbrige/northbridge directory.
Updated patch should fix abuild error and incorporates suggestions

2) the patch implements get_cbmem_toc in chipset specific way if defined.
On Intel targets it should be unchanged. On K8T890 the the cbmem_toc is read from NVRAM. Why you ask? Because we cannot do it as on intel, because the framebuffer might be there making it hard to look for it in memory (and remember we need it so early that everying is uncached)
3) The patch removes hardcoded limits for suspend/resume save area (it was 1MB) on intel. Now it computes right numbers itself.
4) it impelements saving the memory during CAR to reserved range in sane way. First the sysinfo area (CAR data) is copied, then the rest after car is disabled (cached copy is used). I changed bit also the the copy of CAR area is now done uncached for target which I feel is more right.
I think I did not change the Intel suspend/resume behaviour but best would be if someone can test it. Please note this patch was unfinished on my drive since ages and it would be very nice to get it in to prevent bit rotten it again.
Now I feel it is done good way and should not break anything. I did a test with abuild and it seems fine.

Console is meant to be debugging only, and by the time graphics comes up
99% of the risky stuff has already happened. Note: This patch does not remove

-- When building for UMA, reduce the limit for DRAM below 4GB
from E0000000 to C0000000. This is needed to accomodate the
UMA frame buffer.
-- Correct problem where msr C0010010 bits 21 and 22 (MtrrTom2En
and Tom2ForceMemTypeWB) are not set consistently across cores.
-- Enable TOM2 only if DRAM is present above 4GB.
-- Use AMD Tom2ForceMemTypeWB feature to avoid the need for
variable MTRR ranges above 4GB.
-- Add above4gb flag argument to function x86_setup_var_mtrrs. Clearing
this flag causes x86_setup_var_mtrrs() to omit MTRR ranges for
DRAM above 4GB. AMD systems use this option to conserve MTRRs.
-- Northbridge.c change to deduct UMA memory from DRAM size reported
by ram_resource. This corrects a problem where mtrr.c generates an
unexpected variable MTRR range.
-- Correct problem causing build failure when CONFIG_GFXUMA=1 and
CONFIG_VAR_MTRR_HOLE=0.
-- Reserve the UMA DRAM range for AMD K8 as is already done for AMD
family 10h.

is sometimes logged. The reason is that the AP first sets a completion value
such as 0x13, which is what function wait_cpu_state() is waiting for. Then a
short time later, the AP calls function init_fidvid_ap(). This function sets
a completion value of 01. When logging is off, wait_cpu_state is fast enough
to see the initial completion value for each of the APs. But with logging
enabled, one or more APs may go on to complete function init_fidvid_ap, which
sets the completion value to 01. While mostly harmless, the timeout does
increase boot time. This patch eliminates the timeout by making function
wait_cpu_state recognize 01 as an additional valid AP completion value.
