The constant value 0x100000000 is used in linker scripts to calculate

Not doing a hard reset leaves the BOFL0 register cleared, which
prevents the BSP selection from working. To make sure we start
with known values, use the SPAD0 register for soft reset detection.
If there's a value other than 0, do a hard reset.

This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.
As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.
There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.
When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.

Originally, on ChromeBooks, coreboot would provide a modified
u-boot device tree (FDT) to u-boot in CBMEM. However, u-boot
can now create all the information it needs from the coreboot
table and add it to its device tree itself. This means we can
drop this (anyways unused) code.

- Separate Sandybridge from ChromeOS a bit
The Sandybridge code depends on chromeos features a whole lot.
As a first step, provide a code path to look up the MRC cache
without depending on u-boot.
- Move mrc cache handling to separate file
This enables us to handle the MRC cache from ramstage,
where we can write the flash safely (eg. to update the
cache).
Also teach it to lookup the current MRC cache from CBMEM,
as the original data block isn't available anymore.
After all the preparations, finally write to the SPI
as necessary. It's a simple round robin wear levelling
that erases the entire MRC cache region when it's full
and starts from the beginning.

Another bug in the Intel microcode update code that existed since we switched
to LinuxBIOSv2 in 2004:
The inline assembly code that reads the CPU revision from an MSR after running
cpuid(1) trashes registers EBX and ECX. Only ECX was mentioned in the clobber
list. C code running after this function could silently access completely wrong
data, which resulted in the wrong date being printed on microcode updates (and
potentially other issues happening until the C code writes to EBX again)

The current early PM setup that attempts to configure dynamic clock
gating relies on PCIe functions to be enabled that may not be.
Instead of reading port 0 or 4 directly to determine the link width
use the register that refelects the soft strapping options as this
will always be available.
Also add a clear register assignment and break for port 0 in the
switch statement instead of falling through to port 4 as that could
end up setting the slot power limit based on port 4 values instead
of based on port 0.
register 0xE1=0x3f and all other root ports should have 0xE1=0x03.
When port 0 and 4 are disabled they will have 0xE1=0x3C before
being disabled by the pch enable handler.

Background: The PCI spec (3.0-3.2.2.3.4) requires that PCI devices
implement function 0. The Linux Kernel therefore will not enumerate
a PCI device if it does not present a valid config space at function 0.
If a board does not have anything connected to root port 0 and it is
desired to disable the unused ports in order to save power then this
will cause the other downstream PCIe devices to go missing as they
will not be enumerated.
Intel chipsets provide a way to map root port numbers to different PCI
function numbers, thereby avoiding this issue and allowing root port 0
to be turned off.
This change adds a new chip config option 'pcie_port_coalesce' that
will collapse the enabled root ports into a linear map starting at
zero. This option defaults to disabled as it can have a confusing
effect on the system as the declared static devicetree may not match
what is seen at runtime. This option is also forced on if the static
devicetree disables port 0.
When each root port is processed in the early enable stage it looks
for a lower numbered root port that has been disabled and then swaps
the two assigned function numbers.
However the mapping register is write-once so it has to keep track of
the proposed mapping changes until all ports have been processed
before writing out the final map value. At this point it also updates
the function numbers in the static device tree so they are consistent
with the new layout.
There are a few other closely related fixes in this change:
1) There is a power savings opportunity if an entire bank of ports
(0-3 or 4-7) are disabled. This was checking the chipset revision to
look for CougarPoint B1+ stepping and that was not passing on
PantherPoint where this should always be applied. To fix this I added
a function to determine the chipset type based on comparing the upper
byte of the device ID.
2) Apply the same chipset type check fix to the IOBP programming.
3) There is another power savings opportunity to enable dynamic clock
gating on shared PCIe resources which only applies to ports 0 and 4.
However if 0 or 4 is disabled then the later check to enable this
would fail as that device is already hidden.

The chipset enforces static-defined interrupt swizzling on PCIe root
ports so if a port is remapped to a different function it needs to
still report the proper interrupt map to the OS instead of assuming
that function number is equivalent to root port number.
This change also includes an update to the PCH function disable
register which was incorrect for CPT/PPT and would cause unpredictable
behavior if used.
The kernel command line was changed to add 'nomsi' in order to force
PCIe devices to use IO-APIC assigned interrupts and not MSI to ensure
that the mapping is correct.

The sata controller comes up in legacy/normal mode and
is currently put into AHCI mode in romstage.
If that is removed and the controller is left alone until the
ramstage driver (like we do on Stumpy/Lumpy) then the resource
allocator will have configured the device for IDE mode with an
IO address in BAR5. Then when the ramstage driver puts the
controller into AHCI mode it will not have the correct resources
to do the rest of the AHCI setup.
So the controller mode needs to be changed in the enable stage
rather than in the init phase. This same register contains
the port map and it is a R/WO (write once) field so the configured
port map must be written at the same time. For non-AHCI mode
the devicetree map was ignored before but it is used now.
Since the port map register is now written at enable step it
does not need to be written again during init.
With this change the sata port map can be reduced to just port 0
and then U-boot does not have to probe all available ports.

device IDs in a single driver entry. As an example the Intel
{Sandy|Ivy} Bridge SATA driver is being modified to use a single
driver structure for all different SATA controller flavors, a few
more Ivy Bridge IDs are being added as well.
BUG=none
TEST=manual
. modified coreboot brought up an Ivy Bridge platform all the
way to Linux login screen.

The Emerald Lake 2 CRB wasn't designed with ChromeOS in mind, so there aren't
any actual developer mode, recovery mode, or write protect switches, let alone
GPIOs to read them from. Instead, I've commandeered signals connected to GPIOs
which are for other things but which aren't used by hardware or, for instance,
the EC to do something Coreboot doesn't control.
The recovery mode switch is connected to GPIO 22 and is called BIOS_REC on the
schematic. The name is at least very reminiscent of the right thing even if
it's supposed to be used for something else. There's a jumper on the board
labelled J8G1 which can force the line to ground, and if not, there's a switch
on the front of the case which toggles its value. "RECOVER" is for recovery
mode and "KEEP" is for normal mode.
The developer mode switch is connected to GPIO 57 and is called SV_DET on the
schematic. It's connected to a jumper labelled J8E2 on the board and, as far as
I can tell, can't be controlled in any other way. When the jumper is in place
and the pins are shorted, developer mode is selected. When the jumper is
removed, normal mode is selected.
The write protect is connected to GPIO 48 which is called BIOS_RESP on the
schematic. It's connected to a jumper labelled J8E3 which, like j8E2, seems to
be the only way to control the line it's on. When the jumper is in place,
write protect is "disabled", and when it's in place it's "enabled" even though
there's no functional difference.
The input for the recovery mode switch was chosen because of the name it
already had on the CRB, BIOS recovery, and because there's a switch to control
it on the front of the case which makes it easy to get at. The jumpers for
developer mode and recovery mode were chosen because there weren't very many
options available, and of those these were next to each other which should
make them easier to find and work with. It might be a good idea to wire toggle
switches up to the pins of those jumpers so they'll be easy to identify, can
be labelled, and would be easier to work with than little jumpers in the
middle of the motherboard.

This fixes a few cosmetics with the following three boards:
- Intel Emerald Lake 2
- Samsung ChromeBook
- Samsung ChromeBox
The following issues were fixed:
- rely on include path in ASL code instead of specifying relative
paths
- use updated ALIGN_CURRENT in acpi_tables.c
- use preprocessor defines instead of hard coded values where possible

One option to allow using the repo (defaults to no),
one to let boards state that they require it in the
current configuration.
The build system checks out the repo if allowed, and
fails if the repo is requested by the configuration
but not desired by the user.

This code is still using libfdt which was denied for inclusion
in coreboot, so it won't compile as is.
Without MRC cache, waking from suspend won't work, and cold boots are
significantly slower (adds around 300-400ms per channel IIRC).
A rework of this code is currently in the works, but will take a little bit
more time (and should not hold back the mainboards being merged)

AMD supplies their video bios for the Family 14h processor line
with Vendor ID: 1002, Device ID: 9802. This rom should work for
Device IDs 9802-9809. This patch maps all those device IDs to
0x9802 so coreboot will be able to load the vbios. If a vbios
rom using the ACTUAL Device ID is loaded, this function will not
be called.
This file should contain of all Family 14h Graphics PCI IDs so
that they don't need to be overridden on a per mainboard basis.

This is a model fadt.c that I would like to use for updating
several other AMD platforms with after acceptance.
- Updated to match ACPI 3.0b specification and added comments
to reflect that.
- Since smi_cmd is 0, remove commands that rely on it:
acpi_enable, acpi_disable, & pstate_cnt
Add comments to that effect.
- Changed preferred_pm_profile to SOHO Server (platform
specific)
- The southstation platform is legacy free - Updated
iapc_boot_arch and flags to reflect that.
- Added reset_register flag so that operating systems
will actually use the reset_reg. This is important
on legacy free systems.
- Updated Generic Address Structures to use access_size
name in the updated acpi.h. Added access sizes to
the structures where reasonable.
- Removed 64-bit x_firmware_ctl pointer to facs. This was
causing a fwts failure and windows-64 BSOD.
- Added bit width for pm2_cnt_blk and modified gpe0_blk bit
to match the hardware.
