Rearranged the F2A85-M DSDT file to match the functionality found
on Parmer. As with the Parmer implementation, the F2A85-M dsdt.asl
file in the mainboard directory contains only #include references to
the appropriate files.
As with Parmer, some include files have no content but are left as a
template for other platforms and as placeholders for completing the

The VBIOS device ID is set by processor family using the

is rarely a reason why this should be overridden by the mainboard.
Since Kabini includes a default VBIOS vendor/device ID in the
northbridge Kconfig code, remove the setting from the Olive Hill
mainboard settings.

Eliminate an unnecessary copy of the DDI descriptor list and

This patch sets a bit in the Yangtze southbridge to enable
the extra protocol necessary to handle port multiplier chips.
This has been turned on during most of Kabini development
without any notable impact. Olive Hill has an optional daughter
board that incorporates Silicon Image Steel Vines chips. This
change has been tested with and without the daughter board. This
change can be regression tested using any Hudson-based motherboard,
although it has no impact on boards with discreet Hudson/Bolton
southbridges.
This was tested for impact on SATA performance in the absence of
a port multiplier using the IOZone benchmarks within the Phoronix
Test Suite. A SATA 3 hard drive (6.0 Gbps) and an SSD were
connected to the ports on Olive Hill without using the port
multiplier card. The test results contained more run-to-run
variation within the same configuration than was seen in the
aggregate results comparing the interface with and without the
port multiplier protocol additions. In other words, the test
had less accuracy than the impact caused by turning on port
multiplier support.

Taking device_t as a parameter, this allows to alter the PCI config
access handlers. This is useful to add tracing of PCI config writes
for devices having problems to initialise correctly.
On older AMD platform PCI MMIO may not be able to fully configure all
PCI devices/nodes, while MMIO_SUPPORT_DEFAULT would be preferred due
to its atomic nature. So those can be forced to IO config instead.

This change includes an example of how to override it.

The Linux thinkpad_acpi.c driver looks for this string while
reading information about the system it is running on.
This commit does not make the module load but it is one of
several things that the module looks for on a ThinkPad.
The use of 3 defines for the serial number template
seems odd but it's done in a way that eliminates
magic numbers, yet avoids use of strcpy, strlen,
strindex, strchr, or strspan: we can have some
correctness assured at compile time. Also, the
defines can be copy/pasted for other mainboards
and we should void errors due to people not changing
magic numbers.

Split the Parmer, Family 15tn, and Hudson DSDT into groups. This splits
the DSDT table into includable ASL files which carry details specific
to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The
dsdt.asl file in the mainboard directory contains only #include
references to the appropriate files.
Initially, this split was done by moving each piece of functionality
into its own file (e.g. IRQ routing and mapping, processor tree, sleep
states and sleep methods, etc.) and those pieces were #included in
dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d)
with the extant version of the table. Once the new tables were found
to exactly match the existing tables, the pieces were rearranged into
reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.).
Some include files have no content but are left as a template for
other platforms and as placeholders for completing the ACPI
implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl,
sata.asl, etc.).

It might be the case that a file is being loaded from a portion of CBFS which
has already been loaded into a limitted bit of memory somewhere, and we want
to load that file in place, effectively, so that it's original location in
CBFS overlaps with its new location. That's only guaranteed to work if you use
memmove instead of memcpy.

The SOC's built in ROM loads the bootblock and the ROM stage into the on chip
memory before handing over control to the bootblock. To avoid having to add
one or more driver to the bootblock so that it can re-load the ROM stage from
whatever media Coreboot is stored on, we can just take advantage of the copy
that's already there. Loading the RAM stage/payloads won't be so simple,
so the ROM stage and the RAM stage will have to have different media drivers.

This variable wasn't being defined and was defaulting to zero when used in the
ROM stage's linker script. This change defines it as a variable, and gives it
a value which is slightly beyond the end of the bootblock. By making the ROM
stage request to be loaded slightly farther into memory than it was loaded by
the SOC's masked ROM, we ensure that it's moved away from the stage's metadata
instead of on top of it. When it moves the other way, it clobbers important
values like the entry point vefore the bootblock has had a chance to use them.

At least when building with the gnu toolchain, the headers the linker
automatically generate save space for the actual ELF headers in one of the
loadable segments. This creates two problems. First, the data you intended to
be at the start of the image doesn't actually show up there, it's actually the
ELF headers. Second, the ELF headers are essentially useless for firmware
since there's currently nothing to tell you where they are, and even if there
was, there isn't much of a reason to look at them. They're useful in userspace
for, for instance, the dynamic linker, but not really in firmware.
This change adds a PHDRS construct to each of the linker scripts used on ARM
which define a single segment called to_load which does not have the flag set
which would tell the linker to put headers in it. The first section defined in
the script has ": to_load" to tell the linker which segment to put it in, and
from that point on the other sections go in there by default.

Also, we should not be configuring the hardware display port hotplug detect

The workaround of re-opening device in exynos_spi_read has been fixed by the new
correct open/close and xfer procedure. It's safe to be removed now.

The SPI driver (exynos_spi_rx_tx) was implemented with only "read" ability and
only full-duplex mode. To communicate with devices like ChromeOS EC, we need
both output (tx) and half-duplex (searching frame header) features.
This commit adds a spi_rx_tx that can handle all cases we need.

The original Exynos SPI open/close procedure was copied from U-Boot SPL with
some assumptions that only works in SPL stage. For example, it tries to always
work in 4-byte transmission mode with only RX data is swapped, and claims a
packet for initial address command (and with incorrect size).
This commit revises open/close and reset so only the required SPI registers are
configured.

The SPI module in Exynos 5420 didn't follow Coreboot's SPI API standard
(spi-generic.h) and will be a problem when we want to share SPI drivers.
This commit replaces exynos_spi_* by spi_* functions.
Note, exynos_spi_read is kept and changed to a static function because its usage
is different from the standard API "spi_xfer".

For devices with ChromeOS EC on SPI bus, use the standard SPI driver interface
(see spi-generic.h) to exchange data.
Note: Only EC protocol v3 is supported for SPI bus.

Add the new Chrome EC protocol version 3 to Coreboot.
Note, protocol version 3 is not applied on any bus implementations yet.
LPC (x86) and I2C (arm/snow) are still using v2 protocol. The first one to use
v3 protocol will be SPI bus (arm/pit). LPC / I2C will be updated to v3 only
when they are ready to change.

Since EC protocol v3, the packet format will be the same for all buses (inclding
I2C, SPI, and LPC). That will simplify the implementation in each individual bus
driver source file.
To prepare for that, we will move the protocol part into crosec_proto.c:
crosec_command_proto, with bus driver in callback "crosec_io".
