FSP uses PchHdaAudioLink{Hda|Dmic|Ssp|Sndw}Enable UPDs to configure
GPIO pads for audio. However, mainboard is expected to perform all
GPIO configration in coreboot and hence these UPDs must be set to
0. There is no need to expose these UPDs in chip.h and provide
mainboard an option to set these in devicetree.
This change drops PchHdaAudioLink{Hda|Dmic|Ssp|Sndw}Enable UPDs from
chip.h and the corresponding devicetree in mainboards. Currently,
shadowmountain already set these UPDs to 0, whereas adlrvp set these
to 1. But all the ADL boards are correctly configuring the GPIO pads
for audio, so this change should not impact audio for any of these
boards.

couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it

CB:31250 ("soc/intel/cannonlake: Configure GPIOs again after FSP-S is
done") introduced a workaround in coreboot for `soc/intel/cannonlake`
platforms to save and restore GPIO configuration performed by
mainboard across call to FSP Silicon Init (FSP-S). This workaround was
required because FSP-S was configuring GPIOs differently than
mainboard resulting in boot and runtime issues because of
misconfigured GPIOs.
This issue has since been fixed in FSP (verified with FSP v1263 on
hatch). However, there were still 4 boards in coreboot using
`cnl_configure_pads()`. As part of RFC CB:50829, librem_cnl, clevo/cml-u
and system76/lemp9 were tested to ensure that this workaround is no
longer required.
This change drops the workaround using `cnl_configure_pads()` and
updates all mainboards to use `gpio_configure_pads()` instead.

On VCCin there was an oscillation which occurred just as the kernel
started (kernel starting... message). On some devices, this behavior
seems even worse. In previous platforms VCCin toggled for a few ms
and then was stable. For volteer, this happens at the same point in
time for around 40ms. However, it starts oscillating again later in
the boot sequence. Once at the root shell, it seems to oscillate
indefinitely at around 100-200Hz (very variable though). To fix this
we need to control the deep C-state voltage slew rate.We have options
for controlling the deep C-state voltage slew rate through FSP UPDs.
This patch expose the following FSP UPD interface into coreboot:
- AcousticNoiseMitigation
- FastPkgCRampDisable
- SlowSlewRate
We are setting SlowSlewRate for all volteer boards to 2 which is Fast/8.
TGL has a single VR domain(Vccin). Hence, the chip config is updated to
allow mainboards to set a single value instead of an array and FSP UPDs
are accordingly set.

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.

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.

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.)

This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.

FSP has added the Cnvi BT Core enabling in addition to the existing
CnviMode. This change adds the flag at the soc config side (i.e.
soc_intel_tigerlake_config for devicetree). Also, there is no longer PCI host
interface for BT. Therefore, BT core should not use the pci port status to turn
on/off.
TEST: BT enumeration is checked using 'lsusb -d 8087:0026' from OS to make
sure BT is turned on.

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.

The Intel ADL BIOS specification #627270 recommends reserving the
following resources for each PCIe TBT root port:
- 42 buses
- 192 MiB Non-prefetchable memory
- 448 MiB Prefetchable memory
Add a mainboard Kconfig which will auto-select these recommended values,
in addition to PCIEXP_HOTPLUG.
