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.

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.

51cb26d92a SMM: Fix state save map for sandybridge and TSEG
There are enough differences that it is worth defining the
proper map for the sandybridge/ivybridge CPUs.  The state
save map was not being addressed properly for TSEG and
needs to use the right offset instead of pointing in ASEG.

To do this properly add a required southbridge export to
return the TSEG base and use that where appropriate.

998f3a27be Cougar/Panther Point: Compile in ME7 and ME8 code at the same time
In the short term there might be devices with Sandy Bridge CPUs
on mainboards with Panther Point PCHes. While this configuration
option is perfectly valid, coreboot currently ties Sandy Bridge to
Cougar Point and Ivy Bridge to Panther Point. One occurence is in
the ME handling code.

To make coreboot most flexible, compile both ME handlers into
coreboot and decide at runtime which one to use.

b5dfcae097 cs5536: add smbus support in ramstage
With this patch it is possible to use the smbus in ramstage. The
biggest part of the patch is a simple code split into a general
part (smbus.h) and the concrete users (early_smbus.c and cs5536.c).
After the switch from romstage to ramstage the smb base address
has changed, but that is no problem as the new base address is
stored in bar0 of the ISA bridge. It could also be read via msr,
but via PCI it is simpler. I used the following patch as
reference on how to readout the new base address:

3b3a1a1ee6 Provide functions to access arbitrary GPIO pins and vectors
This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.

As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.

There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.

When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.

4aca5d7e66 Fix issue with PCIe power management setup
The current early PM setup that attempts to configure dynamic clock
gating relies on PCIe functions to be enabled that may not be.
Instead of reading port 0 or 4 directly to determine the link width
use the register that refelects the soft strapping options as this
will always be available.

Also add a clear register assignment and break for port 0 in the
switch statement instead of falling through to port 4 as that could
end up setting the slot power limit based on port 4 values instead
of based on port 0.
register 0xE1=0x3f and all other root ports should have 0xE1=0x03.

When port 0 and 4 are disabled they will have 0xE1=0x3C before
being disabled by the pch enable handler.

b9fe01c881 Add an option to enable PCIe root port coalescing
Background: The PCI spec (3.0-3.2.2.3.4) requires that PCI devices
implement function 0.  The Linux Kernel therefore will not enumerate
a PCI device if it does not present a valid config space at function 0.

If a board does not have anything connected to root port 0 and it is
desired to disable the unused ports in order to save power then this
will cause the other downstream PCIe devices to go missing as they
will not be enumerated.

Intel chipsets provide a way to map root port numbers to different PCI
function numbers, thereby avoiding this issue and allowing root port 0
to be turned off.

This change adds a new chip config option 'pcie_port_coalesce' that
will collapse the enabled root ports into a linear map starting at
zero.  This option defaults to disabled as it can have a confusing
effect on the system as the declared static devicetree may not match
what is seen at runtime.  This option is also forced on if the static
devicetree disables port 0.

When each root port is processed in the early enable stage it looks
for a lower numbered root port that has been disabled and then swaps
the two assigned function numbers.

However the mapping register is write-once so it has to keep track of
the proposed mapping changes until all ports have been processed
before writing out the final map value.  At this point it also updates
the function numbers in the static device tree so they are consistent
with the new layout.

There are a few other closely related fixes in this change:

1) There is a power savings opportunity if an entire bank of ports
(0-3 or 4-7) are disabled.  This was checking the chipset revision to
look for CougarPoint B1+ stepping and that was not passing on
PantherPoint where this should always be applied.  To fix this I added
a function to determine the chipset type based on comparing the upper
byte of the device ID.

2) Apply the same chipset type check fix to the IOBP programming.

3) There is another power savings opportunity to enable dynamic clock
gating on shared PCIe resources which only applies to ports 0 and 4.
However if 0 or 4 is disabled then the later check to enable this
would fail as that device is already hidden.

c323036884 Update PCIe Root Port _PRT to handle re-mapped functions
The chipset enforces static-defined interrupt swizzling on PCIe root
ports so if a port is remapped to a different function it needs to
still report the proper interrupt map to the OS instead of assuming
that function number is equivalent to root port number.

This change also includes an update to the PCH function disable
register which was incorrect for CPT/PPT and would cause unpredictable
behavior if used.

The kernel command line was changed to add 'nomsi' in order to force
PCIe devices to use IO-APIC assigned interrupts and not MSI to ensure
that the mapping is correct.

816d081760 Fix SATA port map to only enable port 0
The sata controller comes up in legacy/normal mode and
is currently put into AHCI mode in romstage.

If that is removed and the controller is left alone until the
ramstage driver (like we do on Stumpy/Lumpy) then the resource
allocator will have configured the device for IDE mode with an
IO address in BAR5.  Then when the ramstage driver puts the
controller into AHCI mode it will not have the correct resources
to do the rest of the AHCI setup.

So the controller mode needs to be changed in the enable stage
rather than in the init phase.  This same register contains
the port map and it is a R/WO (write once) field so the configured
port map must be written at the same time.  For non-AHCI mode
the devicetree map was ignored before but it is used now.

Since the port map register is now written at enable step it
does not need to be written again during init.

With this change the sata port map can be reduced to just port 0
and then U-boot does not have to probe all available ports.
