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.

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

This sets up the SMI and SCI inputs on the PCH for Emerald Lake 2 based on my
best interpretation of the schematic. It may not be correct, but it doesn't
seem to cause any problems either.

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.
