This change updates the AMD Agesa code to support the Family 14
rev C0 cpus. It also fixes (again) a ton of warnings, although
not all of them are gone. The warning fixes affect code in the
Family 12 tree as well, so there are some small changes therein.
This code has been tested on a Persimmon and passes Abuild.
This is the first (and largest) of a number of commits to complete
the upgrade.

The previous code does a full flush of the uart after every character.
Unfortunately, this can cause transmission delays on some serial

This patch changes the code so that it does a flush at the end of
every printk instead of at the end of every character. This reduces
the time it takes to transmit serial messages (up to 9% on my Asrock
e350m1 board). It also makes the transmission time more consistent
which is important when performing timing tests via serial
transmissions.

To avoid the Windows BSOD, the uninitialized value TOM1 in the SSDT

patching method, and not the (possibly preferred) AML generation
method. To simplify the patching operation, I moved the AML item

ported to coreboot, the gpp component of this function was called
once for each gpp port, as the gpp port's enable/disable state
became known. A 05/15/2011 change makes the early gpp code run
only once, triggered by processing the 4th gpp port. This method
is not general enough because the 4th gpp port is not enabled on
all boards. With the current change, the early gpp code runs when
the first gpp port is processed. If any gpp ports are enabled, the
first must be enabled. Tested with Win7 and linux on asrock e350m1.
This change will also affect amd inagua, and has not been tested
on that board.

Fixes spurious SMI crashes i've seen, and ACPI/SMM interaction.
For reference, the mail i've sent to ML with the bugreport:
whenever i've docked/undocked the thinkpad from the docking station,
i had to do that twice to get the action actually to happen.
First i thought that would be some error in the ACPI code. Here's a
short explanation how docking/undocking works:
1) ACPI EC Event 0x37 Handler is executed (EC sends event 0x37 on dock)
2) _Q37 does a Trap(SMI_DOCK_CONNECT). Trap is declared as follows:
a) Store(Arg0, SMIF) // SMIF is in the GNVS Memory Range
b) Store(0, 0x808) // Generates I/O Trap to SMM
c) // SMM is executed
d) Return (SMIF) // Return Result in SMIF
I've verified that a) is really executed with ACPI debugging in the
Linux Kernel. It writes the correct value to GNVS Memory. After that,
i've logged the SMIF value in SMM, which contains some random (or
former) value of SMIF.
So i've added the GNVS area to /proc/mtrr which made things work.
I've also tried a wbinvd() in SMM code, with the same result.
After reading the src/cpu/x86/smm/smmhandler.S code, i've recognized
that it starts with:
movw $(smm_gdtptr16 - smm_handler_start +
SMM_HANDLER_OFFSET), %bx
data32 lgdt %cs:(%bx)
movl %cr0, %eax
andl $0x7FFAFFD1, %eax /* PG,AM,WP,NE,TS,EM,MP = 0 */
orl $0x60000001, %eax /* CD, NW, PE = 1 */
movl %eax, %cr0
/* Enable protected mode */
data32 ljmp $0x08, $1f
...which disables caching in SMM code, but doesn't flush the cache.
So the problem is:
- the linux axpi write to the SMIF GNVS Area will be written to Cache,
because GNVS is WB
- the SMM code runs with cache disabled, and fetches SMIF directly from
Memory, which is some other value
Possible Solutions:
- enable cache in SMM (yeah, cache poisoning...)
- flush caches in SMM (really expensive)
- mark GNVS as UC in Memory Map (will only work if OS
really marks that Area as UC. Checked various vendor BIOSes, none
of them are marking NVS as UC. So this seems rather uncommon.)
- flush only the cache line which contains GNVS. Would fix this
particular problem, but users/developers could see other Bugs like
this. And not everyone likes to debug such problems. So i won't like
this solution.

The docking takes place in romstage to have early serial I/O for debugging.
But to keep romstage small and prevent linking the EC code to romstage, set the
status LED's in ramstage.

Overwriting the SMM Area on resume leaves us with
all variables cleared out, i.e., the GNVS pointer
