commit msg copied from
commit id: 64c9f1584c63403207ee85b1d54ca594ae1fbedf
The GPIO drivers in Windows and Linux for the Icelake CPU
have a sparse GPIO map and do not allocate pins contiguously.
Each GPIO group is allocated as 32 pads regardless of whether
the hardware actually has that many in the group.
It appears this originated with a bug in Windows/UEFI and was
carried over to Linux in order to work with existing firmware:
https://lore.kernel.org/patchwork/patch/855244/
In order to support using ACPI GPIOs it is necessary for coreboot
to be compatible with this implementation. The GPIO groups that
are usable by the OS are declared with a pad base which is then
used to compute the number for ACPI GPIOs.

When the BMC firmware module is installed on the KGPE-D16, the
RAM SPD multiplexer lines are disconnected by hardware from the
SP5100 GPIOs and attached to BMC GPIO lines instead.
Set the BMC GPIOs to match the state of the SP5100 GPIOs during
RAM setup.

This patch implements board reset on the Cheza board. The real board
reset used by the operating system uses the PMIC, but unfortunately the
PMIC needs to be configured right for that to work. The PMIC
configuration currently happens in the Qualcomm blob (QcLib) that is run
from romstage, but vboot needs to be able to reboot during verstage
already. Porting all the PMIC initialization code to run in the
bootblock seems excessive (and at odds with the goal of doing as little
as possible before verification), so we'll just do a little hack and ask
the EC to perform a cold reset instead. For vboot purposes, this should
work just as well.
BUG=b:118501305
TEST=Hacked vboot code to call vboot_reboot(), confirmed that board
reset and came back up as expected.

The GPIO pin map for CNL-H does not match with the OS expected
pin numbers. This has been updated to match what is used by the
Linux kernel pinctrl driver and the pad base has been set for
the GPIO groups to match the sparse GPIO map used by the kernel.
I do not have CNL-H hardware to test this so it is verified against
the kernel driver at drivers/pinctrl/intel/pinctrl-cannonlake.c

The GPIO drivers in Windows and Linux for the Cannonlake CPU
have a sparse GPIO map and do not allocate pins contiguously.
Each GPIO group is allocated as 32 pads regardless of whether
the hardware actually has that many in the group.
It appears this originated with a bug in Windows/UEFI and was
carried over to Linux in order to work with existing firmware:
https://lore.kernel.org/patchwork/patch/855244/
In order to support using ACPI GPIOs it is necessary for coreboot
to be compatible with this implementation. The GPIO groups that
are usable by the OS are declared with a pad base which is then
used to compute the number for ACPI GPIOs.
BUG=b:120686247
TEST=tested with write protect GPIO on sarien board. Before this
change the ACPI pin number was 220 which did not correspond to the
pin number in Linux. After this change the ACPI number is 303,
which maps to the correct GPIO in Linux. Now the GPIO value reported
by the kernel changes when the WP pin is toggled in hardware.

If the generic GPIO library is enabled the code that generates the
GPIO table in ACPI should attempt to get the GPIO pin value from
the gpio_acpi_pin() function.
BUG=b:120686247
TEST=Tested on Sarien board to ensure that GPIO pin exported by
Chrome OS for the Write Protect signal is correct.

In some situations the GPIO pad numbers used by the OS are not
contiguous and coreboot must provide a way for ACPI to provide
the expected GPIO number to the OS.
To do this each GPIO group can now have a pad base value, which
will be used as the starting pin number for this group and it
is added to the relative pin number of this GPIO to compute the
ACPI pin number for a particular GPIO.
By default this change has no effect because the existing uses
of INTEL_GPP() will set the pad base to PAD_BASE_NONE and the
GPIO number is used as the ACPI pin number without translation.
