Definition for NAV_FWE BIT was added in commit e6e8b3d
Even if try to set this BIT it was not getting set since PAD_CFG_DW0
mask will make it 0 since this bit was not part of mask.
Adding NAV_FWE to mask will resolve this issue and BIT will be set/unset
as per programming in mainboard.
TEST=Check GPIO register dump and see if BIT is getting set properly.

Intel PDGs starting from Skylake / Sunrise Point state that, different
from the general recommendation in digital electronics, unconnected
GPIOs defaulting to GPIO mode do explicitly not require termination.
The reason for this is, that these GPIOs have the `GPIORXDIS` bit set,
which effectively disconnects the pad from the internal logic by
disabling the input buffer.
This bit - besides `GPIOTXDIS` - can also be set explicitly by using
the gpio macro `PAD_NC(pad, NONE)`.
In some cases, a pull resistor may be required due to bad board design
or when a vendor sets the RX/TX disable bits together with a pull
resistor and schematics are not available to check if the pad is really
unconnected or just unused. In this case the pull resistor should be
kept.
Pads defaulting to native functions usually don't need special handling.
However, when pads requiring external pull-ups are missing these due to
bad board design, they should be configured with `PAD_NC` to disconnect
them internally.
Rewrite the documentation to reflect these new findings.
Also clarify the comment in soc/intel gpio code accordingly.

TGL boards using the Type-C subsystem for USB Type-C ports without a
retimer attached may require a DC bias on the aux lines for certain
modes to work. This patch adds native coreboot support for programming
the IOM to handle this DC bias via a simple devicetree
setting. Previously a UPD was required to tell the FSP which GPIOs were
used for the pullup and pulldown biases, but the API for this UPD was
effectively undocumented.

Earlier we did not have definition for BIT27 for PAD_CFG0 register, we
will use this BIT to enable "virtual wire messaging for native function"
If this bit is enabled, whenever change is detected on the pad, virtual
wire message is generated and sent to destination set by native function.
This bit must be set while enabling CPU PCIe root port programming for
ADL and thus defining a new macro to set native pad function along with
NAF_VWE bit to make GPIO programming easier from coreboot.
BUG=None
BRANCH=None
TEST=Code compilation works fine and if we use this macro to program
GPIO, proper bit is getting set in PAD_CFG register

The only use case for FSP-T in coreboot is for 'Intel Bootguard'
support at the moment. Bootguard can do verification FSP-T but there
is no verification on whether the FSP found by walkcbfs_asm is the one
actually verified as an IBB by Bootguard. A fixed pointer needs to be
used.

From Skylake/Sunrise Point onwards, there are two BIOS_CNTL registers:
one on the LPC/eSPI PCI device, and another on the SPI PCI device. When
the WPD bit changes from 0 to 1 and the LE bit is set, the PCH raises a
TCO SMI with the BIOSWR_STS bit set. However, the BIOSWR_STS bit is not
set when the TCO SMI comes from the SPI or eSPI controller instead, but
a status bit in the BIOS_CNTL register gets set. If the SMI cause is not
handled, another SMI will happen immediately after returning from the
SMI handler, which results in a deadlock.
Prevent deadlocks by clearing the SPI synchronous SMI status bit in the
SMI handler. When SPI raises a synchronous SMI, the TCO_STS bit in the
SMI_STS register is continously set until the SPI synchronous SMI status
bit is cleared. To not risk missing any other TCO SMIs, do not clear the
TCO_STS bit again in the same SMI handler invocation. If the TCO_STS bit
remains set when returning from SMM, another SMI immediately happens and
clears the TCO_STS bit, handling any pending events.
SPI can also generate asynchronous SMIs when the WPD bit is cleared and
one attempts to write to flash using SPI hardware sequencing. This patch
does not account for SPI asynchronous SMIs, because they are disabled by
default and cannot be enabled once the BIOS Interface Lock-Down bit in
the BIOS_CNTL register has been set, which coreboot already does. These
asynchronous SMIs set the SPI_STS bit of the SMI_STS register. Clearing
the SPI asynchronous SMI source should be done inside the SPI_STS SMI
handler, which is currently not implemented. All of this goes out of the
scope of this patch, and is currently not necessary anyway.
This patch does not handle eSPI because I cannot test it, and knowing if
a board uses LPC or eSPI from common code is currently not possible, and
this is beyond the scope of what this commit tries to achieve (fix SPI).
Tested on HP 280 G2, no longer deadlocks when SMM BIOS write protection
is on. Write protection will be enforced in a follow-up.

Lists of changes:
1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS
2. Move MISCCFG_GPIO_PM_CONFIG_BITS definition from intelblock/gpio.h to
soc/gpio.h. Refer to detailed description below to understand the
motivation behind this change.
An advanced GPIO PM capabilities has been introduced since CNP PCH,
refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions.
Now with TGP PCH, additional bits are defined in the MISCCFG register
for GPIO PM control. This results in different SoCs supporting
different number of bits. The bits defined in earlier platforms
(CNL, CML, ICL) are present on TGL, JSL and ADL too. Hence, refactor the
common GPIO code to keep the bit definitions in intelblock/gpio.h, but
the definition of MISCCFG_GPIO_PM_CONFIG_BITS is moved to soc/gpio.h so
that each SoC can provide this as per hardware support.
TEST=On ADL, TGL and JSL platform.

Until now every AML package had to be closed using acpigen_pop_len().
This commit introduces set of package closing functions corresponding
with their opening function names. For example acpigen_write_if()
opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.

All platforms implement those and using a no-op function is not
expected, so it is better to fail the build if the soc specific code
is not implemented.

In pursuit of the goal of eliminating the proliferation of raw region
devices to represent CBFS files outside of the CBFS core code, this
patch removes the get_spd_cbfs_rdev() API and instead replaces it with
spd_cbfs_map() which will find and map the SPD file in one go and return
a pointer to the relevant section. (This makes it impossible to unmap
the mapping again, which all but one of the users didn't bother to do
anyway since the API is only used on platforms with memory-mapped
flash. Presumably this will stay that way in the future so this is not
something worth worrying about.)

I was bugged by spurious "Failed to enable LTR" messages for years.
Looking at the the current algorithm, it is flawed in multiple ways:
* It looks like the author didn't know they implemented a
recursive algorithm (pciexp_enable_ltr()) inside another
recursive algorithm (pciexp_scan_bridge()). Thus, at every
tree level, everything is run again for the whole sub-
tree.
* LTR is enabled no matter if `.set_ltr_max_latencies` is
implemented or not. Leaving the endpoints' LTR settings
at 0: They are told to always report zero tolerance.
In theory, depending on the root-complex implementation,
this may result in higher power consumption than without
LTR messages.
* `.set_ltr_max_latencies` is only considered for the direct
parent of a device. Thus, even with it implemented, an
endpoint below a (non-root) bridge may suffer from the 0
settings as described above.
* Due to the double-recursive nature, LTR is enabled starting
with the endpoints, then moving up the tree, while the PCIe
spec tells us to do it in the exact opposite order.
With the current implementation of pciexp_scan_bridge(), it is
hard to hook anything in that runs for each device from top to
bottom. So the proposed solution still adds some redundancy:
First, for every device that uses pciexp_scan_bus(), we enable
LTR if possible (see below). Then, when returning from the bus-
scanning recursion, we enable LTR for every device and configure
the maximum latencies (if supported). The latter runs again on
all bridges, because it's hard to know if pciexp_scan_bus() was
used for them.
When to enable LTR:
* For all devices that implement `.set_ltr_max_latencies`.
* For all devices below a bridge that has it enabled already.

Currently, `check-fmap-16mib-crossing` compares the offset and end of
each SPI flash region to 16MiB to ensure that no region is placed
across this 16MiB boundary from the start of SPI flash. What really
needs to be checked is that the region isn't placed across the 16MiB
boundary from the end of BIOS region. Thus, current check works only
if the SPI flash is 32MiB under the assumption that the BIOS region
is mapped at the top of SPI flash. However, this check will not work
if a flash part greater than 32MiB is used.
This change replaces the hardcoded boundary value of 16MiB with a
value calculated by subtracting 16MiB from the SPI flash size (if it
is greater than 16MiB). This calculated value is used as the boundary
that no region defined in the flashmap should be placed across.
The assumption here is that BIOS region is always placed at the top of
SPI flash. Hence, the standard decode window would be from
end_of_flash - 16M to end_of_flash (because end_of_flash =
end_of_bios_region). Currently, there is no consistency in the name
used for BIOS region in flashmap layout for boards in
coreboot. But all Intel-based boards (except APL and GLK) place BIOS
region at the end of SPI flash. Since APL and GLK do not support the
extended window, this check does not matter for these platforms.

Perform some cosmetical changes:
* Override the first prerequisite so we can use `$<`.
* Add/remove whitspace to align things (recipe needs to be indented
by a single tab only).
* We can use shell variables inside double quotes. To make the
end of the variable name clear, use braces, e.g. "${x}".
NB. Most of the double quotes are unnecessary. They only change
the way the script would be failing in case of spurious whitespace.
* Break some lines doing multiple things at once.
* To reduce remaining clutter, put reading numbers into a shell
function.
And functional changes:
* No need to spawn `cat`, the shell can redirect input as well as
output (using `<`).
* To read a number from the `fmap_config.h`, we spawned 4 processes
where a single one can achieve the same. With one exception: GNU
awk refuses to parse hex numbers by default. Luckily, it turned
out that we don't need intermediate decimal numbers: Shells can
do arithmetic with hex values as well.

Currently, if everything worked fine, `$fail` will be unset, leading
to the following `if` statement:
if [ -eq 1 ]
Resulting in the error message:
/bin/sh: line 9: [: -eq: unary operator expected
Fix this by removing the whole `if`, we can just use `exit`.

When the SCI_EN bit is set, PM1 and GPE0 events will trigger a SCI
instead of a SMI#. However, SMI_STS bits PM1_STS and GPE0_STS can
still be set. Therefore, when SCI_EN is set, ignore PM1 and GPE0
events in the SMI# handler, as these events have triggered a SCI.
Do not ignore any other SMI# types, since they cannot cause a SCI.
Note that these bits are reserved on APL and GLK. However, SoC-specific
code already accounts for it. Thus, no special handling is needed here.
