Duncan Laurie 54cba3b4ad SMM: Skip locking SPI registers in finalize step
This is a temporary workaround so the SPI bus can be accessed
at runtime in SMM code until the SPI opcode menu is used
properly.

Stefan Reinauer be1ef2329e chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared Data
coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

Duncan Laurie f4d362339f ELOG: Add support for a monotonic boot counter in CMOS
This maintains a 32bit monotonically increasing boot counter
that is stored in CMOS and logged on every non-S3 boot when
the event log is initialized.

In CMOS the count is prefixed with a 16bit signature and
appended with a 16bit checksum.

This counter is incremented in sandybridge early_init which is
called by romstage.  It is incremented early in order notice
when reboots happen after memory init.

The counter is then logged when ELOG is initialized and will
store the boot count as part of a 'System boot; event.

Reboot a few times and look for 'System boot' events in the
event log and check that they are increasing.  Also verify
that the counter does NOT increase when resuming from S3.

Duncan Laurie 22935e1f43 CPU: Set flex ratio to nominal TDP ratio in bootblock
CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired.  To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.

This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.

The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.

On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:

> dmesg | grep "MHz processor"
[    0.004000] Detected 1795.801 MHz processor.

Duncan Laurie 7d2b81c18d ELOG: Add support for flash based event log
This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.

It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.

A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.

The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.

ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign

And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions.  This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.

This is a large commit and by itself it just provides a new
driver that is made available to coreboot.  Without additional
patches it is not very useful, but the end result is an event
log that will contain entries like this:

Duncan Laurie d2e00b92ce SMM: Add heap region and move C handler higher in region
In order to support SPI and ELOG drivers the SMM region
needs to be able to be larger than the previous allocation
below 0x7400.  Now that we have support for 4M TSEG we do
not need to live in this region.

This change adds a 16KB heap region abofe the save state area
at TSEG+64KB and moves the C handler above this.

The heap region is then available for malloc and the C handler
can grow to support flash and event log features.

While updating the memory map comment in assembly stub I also
added a pause instruction to the cpu spin lock as this was

Duncan Laurie 77dbbac7e7 CPU: Add basic support for Nominal Configurable TDP
Ivybridge B0+ CPUs are capable of supporting multiple TDP levels.
This complicates the default case because now the registers that
were reporting max non-turbo ratio are reporting that value for
the highest possible TDP level.

For now this change just forces everything to use the Nominal TDP
values instead of the higher (or lower) levels.

- When building P-state tables, determine the P[1] (max non turbo)
ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after
they are written, which happens after BIOS_RESET_CPL is set.
- Set the current ratio to Nominal ratio at boot.

1) Verify that P-state table is generated properly with
P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12)

PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00
PSS: 1800MHz power 17000 control 0x1200 status 0x1200

2) Verify power limits in MCHBAR match PKG_POWER_LIMIT:

> rdmsr 0 0x610
0x800080aa00dc8088
> mmio_read32 0xfed159a4
0x000080aa
> mmio_read32 0xfed159a0
0x00dc8088

3) Verify turbo activation ratio is set to nominal ratio:

> rdmsr 0 0x64c
0x0000000000000012

4) Check that proper ratio was set at boot on one core only:

> grep 'frequency set to' /sys/firmware/log
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800

Ronald G. Minnich 9764d4c690 Implement stack overflow checking for the BSP
Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.

Break the stack checking out into a separate function, which
we will later use for the APs.

CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000

Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

The raw data section is then included into CBFS as a file named
'microcode_blob.bin' of type 0x53, which is assigned to microcode
storage.
