2ccc0a4d9f soc/intel: Rename and move MISCCFG_GPIO_PM_CONFIG_BITS definition to soc/gpio.h
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.
Without this CL :
GPIO COMM 0 MISCCFG:0xC0 (Bit 6 and 7 enable)

With this CL :
GPIO COMM 0 MISCCFG: 0x00 (Bit 6 and 7 disable)

88f94a9635 lynxpoint/broadwell: Rename LP GPIO config global
Do not use the same name as the non-LP GPIO config. This allows checking
at build-time that a mainboard uses the correct GPIO config format.

Without this commit, there are no build-time errors when using the wrong
format of GPIO config, but there would be undefined behavior at runtime.

Tested by trying to build asrock/b85m_pro4 and hp/folio_9480m after
toggling the `INTEL_LYNXPOINT_LP` Kconfig option (and trimming down the
USB config arrays for asrock/b85m_pro4). In both cases, building failed
because the necessary GPIO config global is not defined, as expected.

This commit introduces set of package closing functions corresponding

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.

a9b44f4c79 spd_bin: Replace get_spd_cbfs_rdev() with spd_cbfs_map()
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.)

1de8708fe5 cbfs: Remove prog_locate() for stages and rmodules
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.

968ef75988 pciexp_device: Rewrite LTR configuration
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.

d09d8de7da soc/intel/common/fast_spi: Fix check-fmap-16mib-crossing check
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.

de85f5ce2a soc/intel/fast_spi/Makefile: Rewrite 16mib check for legibility
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.
