While EC_COMMS_STATUS_PROCESSING flag is still on after it tries
EC_COMMAND_RETRIES times for sending EC_CMD_GET_COMMS_STATUS,
cros_ec_wait_until_complete() doesn't return an error code.
Return -EAGAIN in the case instead.

EC returns EC_RES_IN_PROGRESS if the host command needs more time to
complete. Whenever receives the return code, cros_ec_send_command()
sends EC_CMD_GET_COMMS_STATUS to query the command status.
Separate cros_ec_wait_until_complete() from cros_ec_send_command().
It sends EC_CMD_GET_COMMS_STATUS and waits until the previous command
was completed, or encountered error, or timed out.

SoC features such as GPIO are accessed via a reserved MMIO area,
we don't know its address but can obtain it from the BAR of
the P2SB device, that device is normally hidden so we have to
temporarily unhide it, read address and hide it back.
There are already a few users and at least one more is coming which
require an access to Primary to Sideband (P2SB) bridge in order
to get IO or MMIO BAR hidden by BIOS.
Create a library to access P2SB for x86 devices in a unified way.
Background information
======================
Note, the term "bridge" is used in the documentation and it has nothing
to do with a PCI (host) bridge as per the PCI specifications.
The P2SB is an interesting device by its nature and hardware design.
First of all, it has several devices in the hardware behind it. These
devices may or may not be represented as ACPI devices by a firmware.
It also has a hardwired (to 0s) the least significant bits of the
base address register which is represented by the only 64-bit BAR0.
It means that OS mustn't reallocate the BAR.
On top of that in some cases P2SB is represented by function 0 on PCI
slot (in terms of B:D.F) and according to the PCI specification any
other function can't be seen until function 0 is present and visible.
In the PCI configuration space of P2SB device the full 32-bit register
is allocated for the only purpose of hiding the entire P2SB device. As
per [3]:
3.1.39 P2SB Control (P2SBC)—Offset E0h
Hide Device (HIDE): When this bit is set, the P2SB will return 1s on
any PCI Configuration Read on IOSF-P. All other transactions including
PCI Configuration Writes on IOSF-P are unaffected by this. This does
not affect reads performed on the IOSF-SB interface.
This doesn't prevent MMIO accesses, although preventing the OS from
assigning these addresses. The firmware on the affected platforms marks
the region as unusable (by cutting it off from the PCI host bridge
resources) as depicted in the Apollo Lake example below:
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [io 0x0070-0x0077]
pci_bus 0000:00: root bus resource [io 0x0000-0x006f window]
pci_bus 0000:00: root bus resource [io 0x0078-0x0cf7 window]
pci_bus 0000:00: root bus resource [io 0x0d00-0xffff window]
pci_bus 0000:00: root bus resource [mem 0x7c000001-0x7fffffff window]
pci_bus 0000:00: root bus resource [mem 0x7b800001-0x7bffffff window]
pci_bus 0000:00: root bus resource [mem 0x80000000-0xcfffffff window]
pci_bus 0000:00: root bus resource [mem 0xe0000000-0xefffffff window]
pci_bus 0000:00: root bus resource [bus 00-ff]
The P2SB 16MB BAR is located at 0xd0000000-0xd0ffffff memory window.
The generic solution
====================
The generic solution for all cases when we need to access to the information
behind P2SB device is a library code where users ask for necessary resources
by demand and hence those users take care of not being run on the systems
where this access is not required.
The library provides the p2sb_bar() API to retrieve the MMIO of the BAR0 of
the device from P2SB device slot.
P2SB unconditional unhiding awareness
=====================================
Technically it's possible to unhide the P2SB device and devices on
the same PCI slot and access them at any time as needed. But there are
several potential issues with that:
- the systems were never tested against such configuration and hence
nobody knows what kind of bugs it may bring, especially when we talk
about SPI NOR case which contains Intel FirmWare Image (IFWI) code
(including BIOS) and already known to be problematic in the past for
end users
- the PCI by its nature is a hotpluggable bus and in case somebody
attaches a driver to the functions of a P2SB slot device(s) the
end user experience and system behaviour can be unpredictable
- the kernel code would need some ugly hacks (or code looking as an
ugly hack) under arch/x86/pci in order to enable these devices on
only selected platforms (which may include CPU ID table followed by
a potentially growing number of DMI strings
The future improvements
=======================
The future improvements with this code may go in order to gain some kind
of cache, if it's possible at all, to prevent unhiding and hiding many
times to take static information that may be saved once per boot.

poweroff again
Commit 98f30d0ecf79 ("ACPI: power: Switch to sys-off handler API")
switched the ACPI sleep code from directly setting the old global
pm_power_off handler to using the new register_sys_off_handler()
mechanism with a priority of SYS_OFF_PRIO_FIRMWARE.
This is a problem in special cases where the old global pm_power_off
handler later gets overwritten, such as the Lenovo Tab2 poweroff bugfix
in x86-android-tablets. The old global pm_power_off handler gets run
with a priority of SYS_OFF_PRIO_DEFAULT which is lower then
SYS_OFF_PRIO_FIRMWARE, causing the troublesome ACPI poweroff (which
freezes the system) to run first.
Switch the registering of lenovo_yoga_tab2_830_1050_power_off over to
register_sys_off_handler() with a priority of SYS_OFF_PRIO_FIRMWARE + 1
so that it will run before acpi_power_off() to fix this.

A recent suggested change to the IFS code has shown that the userspace
API needs a bit more work, see:
https://lore.kernel.org/platform-driver-x86/20220708151938.986530-1-jithu.joseph@intel.com/
Mark it as BROKEN before 5.19 ships, to give ourselves one more
kernel-devel cycle to get the userspace API right.

poweroff again
Commit 98f30d0ecf79 ("ACPI: power: Switch to sys-off handler API")
switched the ACPI sleep code from directly setting the old global
pm_power_off handler to using the new register_sys_off_handler()
mechanism with a priority of SYS_OFF_PRIO_FIRMWARE.
This is a problem in special cases where the old global pm_power_off
handler later gets overwritten, such as the Lenovo Tab2 poweroff bugfix
in x86-android-tablets. The old global pm_power_off handler gets run
with a priority of SYS_OFF_PRIO_DEFAULT which is lower then
SYS_OFF_PRIO_FIRMWARE, causing the troublesome ACPI poweroff (which
freezes the system) to run first.
Switch the registering of lenovo_yoga_tab2_830_1050_power_off over to
register_sys_off_handler() with a priority of SYS_OFF_PRIO_FIRMWARE + 1
so that it will run before acpi_power_off() to fix this.

On a multiple package system using Sub-NUMA clustering, there is an issue
in mapping Linux CPU number to PUNIT PCI device when manufacturer decided
to reuse the PCI bus number across packages. Bus number can be reused as
long as they are in different domain or segment. In this case some CPU
will fail to find a PCI device to issue SST requests.
When bus numbers are reused across CPU packages, we are using proximity
information by matching CPU numa node id to PUNIT PCI device numa node
id. But on a package there can be only one PUNIT PCI device, but multiple
numa nodes (one for each sub cluster). So, the numa node ID of the PUNIT
PCI device can only match with one numa node id of CPUs in a sub cluster
in the package.
Since there can be only one PUNIT PCI device per package, if we match
with numa node id of any sub cluster in that package, we can use that
mapping for any CPU in that package. So, store the match information
in a per package data structure and return the information when there
is no match.
While here, use defines for max bus number instead of hardcoding.
