Patrick Georgi a71ce0daa6 Fix lint-002-build-dir-handling
That lint test requires some Kconfig defaults and uses allyesconfig
for that. Unfortunately that also draws in ccache and scanbuild support,
which significantly change the behaviour of the toplevel Makefile.
Notably, the ccache support breaks if no ccache is installed.

Rudolf Marek 7f76290e2d Small SMM fixups
Align the spinlock to the 4 byte boundary (CPU will guarantee atomicity of XCHG).
While at it add the PAUSE instruction to spinlock loop to hint the CPU we are just
spinlocking. The rep nop could not be used because "as" complains that rep is used
without string instructions.

libpayload's license is more liberal than coreboot's. If we are to

even if not strictly necessary.

Rudolf Marek 23b215272d Improve VIA K8M890 HT settings. Use recommended settings for ROMSIP and
for the transmit clock driving control. Unfortunately this is not enough
to make the HT1000 work reliably, therefore blacklist this for now in CPU
HT code. If ever anyone figure out what is wrong, it could be removed. The
downgrading now makes the board work on HT800, which is certainly better than
not at all with a HT1000 CPU.

My Thinkpad appeared dead. After investigation, it turned out
that the RTC Alarm was triggering an RTC PM1 SMI, but the SMI
handler didn't read the status register, so it was triggered again.

This is a really nasty situation, as it means you have to dissemble
your Notebook just to unplug the RTC battery.

Sven Schnelle d8b60a0f2d T60: undock on external power loss
If power is unplugged/lost, we should undock the docking station.
The power loss can also be caused by the fact that the user removed
the thinkpad from the docking station without pressing the Undock button/hotkey
first. Without undocking it on this event, the thinkpad LPC switch will still
connect the Docking connector, which causes crashes when docking it again.

Cristian Măgherușan-Stanciu d367b00c5b Add the coreboot config to CBFS
The CBFS will contain a new file, named 'config' of type 'raw' that is a
stripped-down version of the .config file that was used to build the
current coreboot image. For space savings, all the comments and empty
lines were removed from the original config, except for one that lists
the coreboot git revision that's built into the image.

This is done in order to easily reproduce the work of  someone else when
only having their ROM image. In theory the reproduce could even be
automated by a new dedicated make target.

This should work even with abuild now.

Scott Duplichan 8fed77ae4c ASRock E350M1: Configure SB800 GPP ports to support onboard pcie nic
Scott Duplichan's patch from the mailing list:
sb800 cimx wrapper: Run the complete sb800 cimx sbBeforePciInit() function
once, after determining device 0x15 function enables.

1) Update the asrock e350m1 devicetree.cb to match the hardware.
2) Change the way the sb800 cimx wrapper code works. The original
cimx code calls sb800 cimx function sbBeforePciInit() once. When
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.

Sven Schnelle 47b3fb403d SMM: flush caches after disabling caching
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.

Sven Schnelle 00d46499a2 T60: set dock LED's in mainboard.c
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.

Sven Schnelle bfe8e5186e SMM: don't overwrite SMM memory on resume
Overwriting the SMM Area on resume leaves us with
all variables cleared out, i.e., the GNVS pointer
is no longer available, which makes SMIF function
calls impossible.
