CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Factor out some common expressions.
Add an error message when coreboots hangs waiting for a pstate
that never comes (it happened to me), and throw some
paranoia at it for good mesure.
If I understood BKDG fam10 CPUs never need a software initiated vid transition,
because the hardware knows what to do when you just request
a Pstate change if the cpu is properly configured. In fact
unifying a little what PVI and SVI do was better for my board (SVI).
So I drop transitionVid, which I didn't understand either (why
did it have a case for PVI if it is never called for PVI ?
Why did the PVI case distinguigh cpu or nb when PVI is
theoretically single voltage plane ? ).

I didn't understand quite why it did that iwth F3xA0 (Power
Control Misc Register) so I moved Pll Lock time to rules in defaults.h
and reimplemented F3xA0 programming. A later patch will remove
a part I don't know what's mean to do.

Bring F3xD4 (Clock/Power Control Register 0) more in line
with BKDG i more cases. It requires looking at the CPU package type
so I add a function for that (in the wrong place?) and some

After this patch, tilapia can run in higher memory frequency.
To test the high frequency, dont forget to change the freq limit in
mcti_d.c:
static void mctGet_MaxLoadFreq(struct DCTStatStruc *pDCTstat)
{
pDCTstat->PresetmaxFreq = 800;

-- 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.
Tested with mahogany on ECS A780G-GM with 2GB and 4GB.

While reviewing impact of this change it seems code for erratum 531 was not in
sync with current docs. I have checked uses of AMD_FAM10_ALL, but I
haven't looked up the docs for all of them, at first sight it seems ok
to include all FAM10 revisions in this mask.
Apply errata 531 only to revisions listed in Revision Guide for AMD Family10h
processors (#41322) rev 3.74 June 2010. Before it was applied also to
DR-B0, DA-C3 or HY-D0 which are not affected according to current docs.

Moving "mct_AfterGetCLT(pMCTstat, pDCTstat, dct);" out of the "if" is the

Revision ID of 0x100F62 is DA-C2, instead of RB-C2 which was incorrectly
defined in raminit_amdmct.c. RB-C2's ID is 0x100F42. The Erratas applied to
them are almost the same.
Issues:
1. I really dont know what their nicknames are (Shanghai C2 or something).
2. About the mc_patch_01000086.h, I dont know if it is allowed to be released.
If you really need it, please contact AMD Inc to see if it is public.
3. My RB-C2 is Socket type AM3, which needs DDR3 support. Probably your RB-C2
doesnt need DDR3. If it does and you really need it, please contack AMD Inc
to see if it is allowed to release DDR3 code.
