d8a2c1fb17 southbridge/amd: Add LPC bridge acpi path for Family14 and SB800
Adds the necessary plumbing for acpi_device_path() to find the LPC
bridge on the AMD Family14 northbridge with an SB800 southbridge.
This is necessary for TPM support since the acpi path to the LPC bridge
(_SB.PCI0.ISAB) doesn't match the built-in default in tpm.c
(_SB.PCI0.LPCB).

97e13d84c3 nb/intel/x4x: Fix raminit on reset path
Previously the raminit failed on hot reset and to work around this
issue it unconditionally did a cold reset.

This has the following issues:
* it's slow;
* when the OS issues a hot reset some disk drives expect their 5V
  power supply to remain on, which gets cut off by a cold reset,
  causing data corruption.

To fix this some steps in raminit must be ommited on the reset path.
This includes receive enable calibration.
To achieve this it stores receive enable results in RTC nvram for them
to be rewritten on the resume path.
Note: The same thing needs to be done on the S3 resume path.

Calling a hot reset after raminit "outb(0x6, 0cf9)" works.

561bebfbaa drivers/intel/gma/vbt: Add Kconfig symbol for SSC ref
The selection of the SSC reference frequency for LVDS was based on a
completely unrelated clock.

The `ssc_freq` flag should be set when the SSC reference runs at a
different frequency than the general display reference clock (DREF).
For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
reference always differs from the display reference clock (i945: 66Mhz
SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
newer, it's the same frequency for SSC/non-SSC (120MHz).  The only,
currently supported platform with a choice seems to be Pineview, where
the alternative is 100MHz vs. the default 96MHz.

1853781748 nb/intel/945gc: Hardcode the integrated graphic frequencies
The code to set the igd frequencies is written with the mobile version
of the 945 chipset in mind and seems to cause cause strange igd
related problems on the desktop versions.

Some possible problems are:
* on 800MHz fsb CPUs the igd sometimes has artifacts on the screen;
* on 800MHz fsb CPU memtest results vary a lot;
* since a commit 45e11aa0a5 "Add/Combine Broadwell Chromebooks using
  variant board scheme" that does not affect this northbridge, the
  display shows garbage as soon as Linux (4.8) modesets the display.

A fix is to hardcode the core display and render clocks to their
maximum, potentially also improving graphical performance.
Vendor bios on all boards in coreboot with this northbridge have the
same value in this PCI config address.

TESTED on P5GC-MX (display works fine again in Linux) and
user reports of it making GA-945GCM-S2L run more stable.

a132892de6 amd/pi: Make BottomIo position configurable
Some PCI peripherals, such as FPGA accelerators, require a great amount
of memory mapped IO. This patch allows the user to select at build time
the bottom IO to leave enough space for such devices.

We cannot calculate this value at runtime because it has to be set
before the PCI devices are enumerated.

62902ca45d sb/ich7: Use common/gpio.h to set up GPIOs
This is more consistent with newer Intel targets.

This a static struct so it is initialized to 0 by default.
To make it more readable:
* only setting to GPIO mode is made explicit;
* only pins in GPIO mode are either set to input or output since this
  is ignored in native mode;
* only output pins are set high or low, since this is read-only on
  input;
* blink is only operational on output pins, non-blink is not set
  explicitly;
* invert is only operational on input pins, non-invert is not set
  explicitly.

75a3d1fb7c amdfam10: Perform major include ".c" cleanup
Previously, all romstages for this northbridge family
would compile via 1 single C file with everything
included into the romstage.c file (!)

This patch separates the build into separate .o modules
and links them accordingly.

Currently compiles and links all fam10 roms without
breaking other roms.

Both DDR2 and DDR3 have been completed

TESTED on REACTS: passes all boot tests for 2 boards
 ASUS KGPE-D16
 ASUS KFSN4-DRE

Some extra changes were required to make it compile
otherwise there were unused functions in included "c" files.
This is because I needed to exchange CIMX
for the native southbridge routines. See in particular:
 advansus/a785e-i
 asus/m5a88-v
 avalue/eax-785e

A followup patch may be required to fix the above boards.

c86c6b33e8 intel cache-as-ram: Move DCACHE_RAM_BASE
Having same memory region set as both WRPROT and WRBACK
using MTRRs is undefined behaviour. This could happen if
we allow DCACHE_RAM_BASE to be located within CBFS in SPI
flash memory and XIP romstage is at the same location.

As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.

There are no reasons to have this as board-specific setting.
