8e079000dc nb/i945/gma.c: Refactor panel setup
This reuses some of gm45 code to set up the panel.

Panel start and stop delays and pwm frequency can now be set in
devicetree.

Linux does not make the difference between 945gm and gm45
for panel delays, so it is safe to assume the semantics of those
registers are the same.

The core display clock is computed according to "Mobile Intel® 945
Express Chipset Family" Datasheet.

This selects Legacy backlight mode since most targets have some smm
code that rely on this.

This sets the same backlight frequency as vendor bios on Thinkpad X60
and T60.

A default of 180Hz is selected for the PWM frequency if it is not
defined in the devicetree, this might be annoying for displays that
are LED backlit, but is a safe value for CCFL backlit displays.

97a4b3edf0 binaryPI platforms: Drop any ACPI S3 support
No board with binaryPI currently supports HAVE_ACPI_RESUME. For
platforms with PSP the approach is also very different from what
we previously had here.

Furthermore, s3_resume.[ch] files under cpu/amd/pi do not
distinguish between NonVolatile and Volatile buffers of S3 storage.
This means the Volatile buffer that is maintained and available in
CBMEM is unnecessarily copied to SPI flash. This has been fixed on
open-source AGESA directory, so development of S3 suspend support
with binaryPI is better continued with that.

Unfortunately there are further complications and indications that
open-source AGESA may have always had a low-memory corruption
issue. This has to be investigated separately before restoring
or claiming S3 is supported on binaryPI.

b2bb6ad2a7 agesawrapper: Fix endless loop on bettong
AGESA AmdInitEarly() reconfigures the lapic timer in a way that
conflicts with lapic/apic_timer.

This results in an endless loop when printk() is called after
AmdInitEarly() and before the apic_timer is initialized.

This patch forces a reconfiguration of the timer after
AmdInitEarly() is called.

Codepath of the endless loop:

printk()->
  (...)->
    uart_tx_byte->
      uart8250_mem_tx_byte->
        udelay()->
          start = lapic_read(LAPIC_TMCCT);
	  	do {
			value = lapic_read(LAPIC_TMCCT);
		} while ((start - value) < ticks);
         [lapic_read returns the same value after AmdInitEarly()]

This reverts commit fec8872c9d.

The commit introduced a regression which is causing MC4 failures
when 8 RDIMMs are populated in a configuration with a single CPU
package. Using just 4 RDIMMs, the failure does not occur.

After reverting the commit, I tested configurations with
1 CPU (8x8=64GB) and 2 CPU packages (16x8=128GB) using an
Opteron 6276. The MC4 failures did not occur anymore.

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.

Since it checks for DDR3 style checksums, it's a more appropriate name.
Also make its configuration local for a future code move.

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.

f6776fa62c amd/amdht: Fix format security errors
Ubuntu’s default compiler flags for GCC [1][2] include `-Wformat
-Wformat-security`, causing errors similar like the one below.

```
    CC         romstage/northbridge/amd/amdht/ht_wrapper.o
src/northbridge/amd/amdht/ht_wrapper.c: In function 'AMD_CB_EventNotify':
src/northbridge/amd/amdht/ht_wrapper.c:124:4: error: format not a string literal and no format arguments [-Werror=format-security]
    printk(log_level, event_class_string_decodes[evtClass]);

```

Fix that, by explicitly using a format string.

eee4f6b224 nb/x4x/raminit: Fix programming dram timings
The results were obtained by comparing the MCHBAR registers of vendor bios
with coreboot at the same dram timings.

This fixes 2 issues:
* 1333MHz fsb CPUs were limited to 667MHz ddr2 speeds, because with
  800MHz raminit failed;
* 1067MHz fsb CPUs did not boot when second dimm slot was populated.

TESTED on ga-g41m-es2l on 800, 1067 and 1333MHz CPUs with
DDR2 667 and 800MHz dimms.
