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
added to the C code in latest upstream rebase.

Dump sympbols from smm.elf binary to see the new regions:

00010000 B _heap
00014000 B _eheap
00014000 T _smm_c_handler_start
0001b240 T _smm_c_handler_end

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

39fea6e2a8 Add microcode blob processing
When microcode storage in CBFS is enabled, the make system is supposed
to generate the microcode blob and place it into the generated ROM
image as a CBFS component.

The microcode source representation does not change: it is still an
array of 32 bit constants. This new addition compiles the array into a
separate object file and then strips all sections but data.

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.

In the last entry the state was getting set to 0:

Package (0x04)
{

  {
    Register (FFixedHW,
              0x01,               // Bit Width
              0x02,               // Bit Offset
              0x0000000000000030, // Address
              0x01,               // Access Size
              )
  },
  0x00000000,                     // State
  0x0000005A,                     // Latency
  0x000000C8                      // Power

Now it is properly identifed as state 3:

305b19dd7a Remove code that enables/disables VMX in coreboot on chromebooks.
There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.

2. On the CPU on link, there is something about trying to set the lock
bit that is getting a GPF.

3. It's the wrong place and time to set it. Once controlled, they can't
be changed in the kernel. The kernel is what should control this
feature, not the BIOS, as we have learned time and time again. If
somebody is in as root and can start a VM, you have a lot more to
worry about than someone starting a guest virtual machine.

de3dde46fd AMD: Fix GFXUMA with 4GB or more RAM
Northbridge code incorrectly adjusted the last cacheable memory
resource to accomodate room for UMA framebuffer. If system had
4GB or more memory that last resource is not below 4GB and not
the one where UMA is located.

There are three consequences:

The last entry in coreboot memory table is reduced by uma_memory_size.

Due the incorrect code in northbridge code state.tomk,
end of last resource below 4GB, had not been adjusted.
Incrementing that by uma_memory_size diverts a region
possibly claimed for MMIO to RAM, as TOP_MEM is written.

Since the UMA framebuffer did not have IORESOURCE_CACHEABLE,
it was ignored from the MTRR setup and not set uncacheable.

The setting of TOP_MEM and TOP_MEM2, as well as all the MTRRs,
should be copied from BSP to all APs instead of deriving the data
separately for each Logical CPU.

042c1461fb Use broadcast SIPI to startup siblings
The current code for initializing AP cpus has several shortcomings:

- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
  there's more than one physical CPU, and CPUs are of different type

Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.

3b5a9edcb2 Fix register corruption during Intel Microcode update
Another bug in the Intel microcode update code that existed since we switched
to LinuxBIOSv2 in 2004:

The inline assembly code that reads the CPU revision from an MSR after running
cpuid(1) trashes registers EBX and ECX. Only ECX was mentioned in the clobber
list. C code running after this function could silently access completely wrong
data, which resulted in the wrong date being printed on microcode updates (and
potentially other issues happening until the C code writes to EBX again)

ea37a21acf Add support for Intel Turbo Boost feature
From wikipedia:
Intel Turbo Boost is a technology implemented by Intel in certain
versions of their Nehalem- and Sandy Bridge-based CPUs, including Core
i5 and Core i7 that enables the processor to run above its base
operating frequency via dynamic control of the CPU's "clock rate".
It is activated when the operating system requests the highest
performance state of the processor.

abdf15f40b Apply cache-as-ram conditionally on socket mPGA604
The socket mPGA604 is for P4 Xeon which to my knowledge is always
HT-enabled. I assume the existing usage of car/cache_as_ram.inc
on socket_mPGA604, namely the Tyan S2735, as broken.

Existing car/cache_as_ram.inc has invalid SIPI vector and it does
not initialise AP CPU's to activate L2 cache.

Other mPGA604 boards are not affected, as they have not been
converted to CAR.

7dfe32c540 Add support for RAM-less multi-processor init
For a hyper-threading processor, enabling cache requires that both the
BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram
implementation, partial multi-processor initialisation precedes
raminit and AP CPUs' 16bit entry must be run from ROM.

The AP CPU can only start execute real-mode code at a 4kB aligned
address below 1MB. The protected mode entry code for AP is identical
with the BSP code, which is already located at the top of bootblock.
This patch takes the simplest approach and aligns the bootblock
16 bit entry at highest possible 4kB boundary below 1MB.

The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR
used by the CAR code in romstage. Adress is not expected to ever
change, but if it does, link will fail.

7389fa945f MTRR: add alternate allocation method for odd memory maps
With >= 4GB memory installed we get a memory map split in the middle
due to remap that has boundaries that are inconveniently aligned for
MTRRs due to the various UMA regions.

0000MB-2780MB  2780MB  RAM     (writeback)
2780MB-2782MB     2MB  TSEG    (uncached/SMRR)
2782MB-2784MB     2MB  GFX GTT (uncached)
2784MB-2816MB    32MB  GFX UMA (uncached)
2816MB-4096MB  1280MB  EMPTY   (N/A)
4096MB-5368MB  1272MB  RAM     (writeback)
5368MB-5376MB     8MB  ME UMA  (uncached)

The default MTRR allocation method of trying to cover everything
with one MTRR and then carve out a single uncached region does
not work for the GPU aperture which needs write-combining type,
and it also has issues trying to cover the uneven boundaries
in the avaiable variable MTRRs.

My goal was to make a minimal set of changes and avoid modifying
behavior on existing systems with an algorithm that is not always
optimal for a typical memory layout.  So the flag 'above4gb=2'
will change these allocation behaviors:

1) Detect the number of available variable MTRRs rather than
limiting to hardcoded value.  We need every last MTRR.

2) Don't try to cover all RAM with one MTRR, instead let each
RAM region get covered independently.

3) Don't assume uma_memory_base is part of the last region
and increase the size of that region.  In this case the UMA
region is carved out from the lower memory region and it is
already declared as part of the ram region.

4) If a memory region can't be covered with MTRRs >= 16MB then
instead make a larger region and trim it with uncached MTRRs.

8b28d50cdd Intel cpus: Fix deadlock on hyper-threading init
Only the BSP CPU was able to start its hyper-threading CPU siblings.
When an AP CPU attempts this it calls start_cpu() within start_cpu(),
deadlocking the system with start_cpu_lock.

At the time intel_sibling_init() is run, the BSP CPU is still
walking the cpu_bus linked list in lapic_cpu_init: start_other_cpus().
A sibling CPU appended at the end of this list will get started.

Also fail compile with #error if SERIAL_CPU_INIT==0, as microcode
updates on hyper-threading sibling CPUs must be serialized.

Tested with HT-enabled P4 Xeons on dual-socket604 platform.
