9745fb0747 platform/x86/intel: Add Primary to Sideband (P2SB) bridge support
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.

b1d288d9c3 platform/chrome: cros_ec_proto: Rename cros_ec_command function
cros_ec_command() is the name of a function as well as a struct, as such
it can confuse indexing tools (like ctags). Avoid this by renaming it to
cros_ec_cmd(). Update all the callsites to use the new name.

This patch is a find-and-replace, so should not introduce any functional
changes.

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
 "This series has been 12 years in the making, it mostly finishes the
  work that was started with the founding of Linaro to clean up platform
  support in the kernel.

  The largest change here is a cleanup of the omap1 platform, which is
  the final ARM machine type to get converted to the common-clk
  subsystem. All the omap1 specific drivers are now made independent of
  the mach/*.h headers to allow the platform to be part of a generic
  ARMv4/v5 multiplatform kernel.

  The last bit that enables this support is still missing here while we
  wait for some last dependencies to make it into the mainline kernel
  through other subsystems.

  The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
  at the point of allowing multiplatform kernels, this work gets
  completed here along with a few additional cleanup. At the same time,
  the s3c24xx and s3c64xx are now deprecated and expected to get removed
  in the future.

  The PXA and OMAP1 bits are in a separate branch because of
  dependencies. Once both branches are merged, only the three Intel
  StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
  need separate kernels, and there are no plans to include these"

c9bc1a0ef9 platform/chrome: cros_ec_lpcs: reserve the MEC LPC I/O ports first
Some ChromeOS EC devices (such as the Framework Laptop) only map I/O
ports 0x800-0x807. Making the larger reservation required by the non-MEC
LPC (the 0xFF ports for the memory map, and the 0xFF ports for the
parameter region) is non-viable on these devices.

Since we probe the MEC EC first, we can get away with a smaller
reservation that covers the MEC EC ports. If we fall back to classic
LPC, we can grow the reservation to cover the memory map and the
parameter region.

cros_ec_lpc_probe also interacted with I/O ports 0x800-0x807 without a
reservation. Restructuring the code to request the MEC LPC region first
obviates the need to do so.

Only the pxafb driver uses this header, so move it into the
same directory. The SMART_* macros are required by some
platform data definitions and can go into the
linux/platform_data/video-pxafb.h header.

57b888ca25 platform/chrome: Re-introduce cros_ec_cmd_xfer and use it for ioctls
Commit 413dda8f2c ("platform/chrome: cros_ec_chardev: Use
cros_ec_cmd_xfer_status helper") inadvertendly changed the userspace ABI.
Previously, cros_ec ioctls would only report errors if the EC communication
failed, and otherwise return success and the result of the EC
communication. An EC command execution failure was reported in the EC
response field. The above mentioned commit changed this behavior, and the
ioctl itself would fail. This breaks userspace commands trying to analyze
the EC command execution error since the actual EC command response is no
longer reported to userspace.

Fix the problem by re-introducing the cros_ec_cmd_xfer() helper, and use it
to handle ioctl messages.

5224f79096 treewide: Replace zero-length arrays with flexible-array members
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)

@@
identifier S, member, array;
type T1, T2;
@@

struct S {
  ...
  T1 member;
  T2 array[
- 0
  ];
};

UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

0177212e27 mtd: spi-nor / spi / MFD: Convert intel-spi to SPI MEM
Merge series from Mika Westerberg <mika.westerberg@linux.intel.com>:

Based on discussion on the patch I sent some time ago here:

  http://lists.infradead.org/pipermail/linux-mtd/2021-June/086867.html

it turns out that the preferred way to deal with the SPI flash controller
drivers is through SPI MEM which is part of Linux SPI subsystem.

This series does that for the intel-spi driver. This also renames the
driver to follow the convention used in the SPI subsystem. The first patch
improves the write protection handling to be slightly more safer. The
following two patches do the conversion itself. Note the Intel SPI flash
controller only allows commands such as read, write and so on and it
internally uses whatever addressing etc. it figured from the SFDP on the
flash device.

e23e5a05d1 mtd: spi-nor: intel-spi: Convert to SPI MEM
The preferred way to implement SPI-NOR controller drivers is through SPI
subsubsystem utilizing the SPI MEM core functions. This converts the
Intel SPI flash controller driver over the SPI MEM by moving the driver
from SPI-NOR subsystem to SPI subsystem and in one go make it use the
SPI MEM functions. The driver name will be changed from intel-spi to
spi-intel to match the convention used in the SPI subsystem.

cd149eff8d mtd: spi-nor: intel-spi: Disable write protection only if asked
Currently the driver tries to disable the BIOS write protection
automatically even if this is not what the user wants. For this reason
modify the driver so that by default it does not touch the write
protection. Only if specifically asked by the user (setting writeable=1
command line parameter) the driver tries to disable the BIOS write
protection.
