According to the IT8728F datasheet it is possible to add an extra delay
between 3VSBSW# being set and PWRGD3 being set during resume from
Suspend-to-RAM. This is enabled in the special function selection
register, the default being 0.
This is also useful for the IT8720F although this chip does not have the
PWRGD3 output. On the corresponding pin it has PWROK2, which the setting
then seems to apply to.
The datasheet for the IT8720F marks the corresponding bit as reserved,
but the vendor BIOS of an Acer Aspire M3800 sets it anyway. Without
setting the bit, coreboot fails to resume from S3. Oscilloscope
measurements have shown that setting the bit increases the delay between
3VSBSW# being set and PWROK2 being set from around 1 us to 140 ms. The
actual use of PWROK2 on the board design is unclear - the only
destination it seems to reach is a pin header near the SuperIO marked as
"GPIO1".

When booting from the RO region of a VBOOT enabled ROM, there shouldn't
be a reliance on anything outside of the RO section. This includes the
APOB_NV region (similar to the MRC cache region). By skipping the

use the region when booting.
The APOB_NV region is still used for the VBOOT RW sections.

The Linux kenerl driver for AMD gpu currently has a floor
value of 12 for brightness settings (AMDGPU_DM_DEFAULT_MIN_BACKLIGHT).
AMD indicates they did this because they were concerned with certain
panels flickering at lower backlight values. However, for unaffected
panels it's desirable to be able to have the panel "turn off" at
the lowest backlight setting. The only way to do that is to provide
ATIF bindings that indicate backlight range.
Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full
range for the backlight setting. If needed, this path can be built upon
for fuller support, but for the time being this is the only thing
necessary to make the backlight be full range.

The GDT loading did work fine on x86_64 a few months ago, but today it
only works in QEMU, but not on real hardware or KVM-enabled QEMU. This
might be related to toolchain changes.
Use 64bit GDT loading on x86_64 and force the assembler to generate a
64bit address load on the GDT. This will make sure no 32bit (signed)
displacement op is being generated, which points to the wrong address
in longmode.
Verified using readelf and made sure no R_X86_64_32S relocation symbol

With CSE-lite enabled, we were going through the lengthy memory
training procedure twice on the first power-on boot or after full BIOS
SPI flash update. This moves the global reset performed to achieve the
CSE-lite RO to RW reboot to a later boot phase so that it happens
after the memory training data has been written to the MRC cache. Now,
the 2nd (and subsequent) reboot can utilize the memory training data
established during the 1st boot.
This reduces the first boot time by about 20s on a 16GB system.
Looking at the timing stats form cbmem, the normal boot penalty is
about 300ms - mostly attributed to running FspSiliconInit a 2nd

* Enable optional x86_64 romstage, postcar and ramstage
* Add Kconfig for x86_64 compilation
* Add documentation for x86 qemu mainboards
* Increase CAR stack as x86_64 uses more than 0x4000 bytes
Working:
* Boots to Linux
* Boots to SeaBIOS
* Drops to protected mode at end of ramstage
* Enumerates PCI devices
* Relocateable ramstage
* SMM

When compiled in RAMSTAGE use the segments for ramstage.
Allows to call this assembly code in ramstage to exit long mode.
The next commit makes use of this.
Tested on qemu:
Still boots on x86_64.

* On ARCH_RAMSTAGE_X86_64 jump to the payload in protected mode.
* Add a helper function to jump to arbitrary code in protected mode,
similar to the real mode call handler.
* Doesn't affect existing x86_32 code.
* Add a macro to cast pointer to uint32_t that dies if it would overflow
on conversion
Tested on QEMU Q35 using SeaBIOS as payload.
Tested on Lenovo T410 with additional x86_64 patches.

The AM335X is a SoC, so should be in the soc tree.
This moves all the existing am335x code to soc/ and updates any
references. It also adds a soc.c file as required for the ramstage.

Implements fit_payload_arch for the arm (aarch32) architecture, so that
FIT images can be used. The implementation is very similar to the
existing implementations for arm64 and riscv, and has mostly been
lifted from these other ports.
TEST: Booted Beaglebone Black (in progress port, to be submitted soon!)
with a FIT image containing a 5.4 kernel, dtb and initramfs.

In order to log gpio events for wake purposes the state
of the gpio subsystem should be snapshotted. Add the ability
to capture state of gpio subystem as well as saving up to 16
gpios that indicate their wake status.
Likewise, provide the eventlog additions based on state.
