The pch_smbus_init() function contains code to enable clock gating for
the SMBus controller. Unfortunately this code is buggy and leads to a
hanging system with the latest microcode version.
The hang occurs as follows:
The clock gate register is mapped into RCBA space. After reading the
RCBA address from the LPC device config space no mask is applied to the
value (only bits 31..14 are valid while bit 0 is the enable bit). For
this reason the final address is off by one. The old microcodes at least
allowed this unaligned access to the RCBA space. With the latest
microcode this access leads to CPU hang.
Once this is fixed the next issue occurs: After setting the clock
gating bit for SMBus (bit 5) the SMBus controller disappears from the
PCI bus completely and hence no usage of it is possible anymore.
To fix this issue the clock gating code is completely removed as it was
intentionally meant to enable clock gating on the SMB_CLK line and not
the clock gating on the PCIe interface of the SMBus controller.
This issue is known already and was discussed on the mailinglist:

dimm_info.serial had a strange contract. The SPD spec defines a 4 byte
serial number. dimm_info.serial required a 4 character ascii string with
a null terminator.
This change makes the serial field so it matches the SPD spec.
smbios.c will then translate the byte array into hex and set it on the
smbios table.
There were only two callers that set the serial number:
* haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so
it already matches the new contract.
* amd_late_init.c: Previously copied the last 4 characters. Requires
decoding the serial number into a byte array.
google/cyan/spd/spd.c: This could be updated to pass the serial number,
but it uses a hard coded spd.bin.
Testing this on grunt, dmidecode now shows the full serial number:

If the SoC is VT-d capable, write an ACPI DMAR table. The entry for the
GFXVTBAR is only generated if the IGD is enabled.

We use the usual static addresses 0xfed90000/0xfed91000 for the GFX
IOMMU and the general IOMMU respectively. These addresses have to be
configured in MCHBAR registers (maybe, who knows, the blob is undocu-
mented), advertised to FSP and reserved from the OS.
The new devicetree option `ignore_vtd` allows to retain the old beha-
viour (do whatever pre-set UPD values suggest).
We also let FSP set up distinct BDFs for messages originating from the
I/O-APIC and the HPET.

Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

The <gpio.h> API is supposed to include a gpio_set() function that just
toggles the state of a GPIO already configured as an output, even though
we rarely need it since gpio_output() can already be used to initialze a
GPIO to a default value while configuring it as an output. This function
was forgotten on Rockchip, so this patch adds it now.
