57cd50cd6a ichspi: Add support for Panther Lake
This patch adds Panther Lake support into flashrom as per Intel
Panther Lake SPI programming doc, number: 815466.

BUG=b:347669091
TEST=Flashrom is able to detect PTL SPI DID and show chipset name as
below:

> flashrom --flash-name
....
Found chipset "Intel Panther Lake-U/H 12Xe".
....
> flashrom -p internal --ifd -i fd -i bios -r /tmp/bios.rom
....
Reading ich_descriptor... done.
Assuming chipset 'Panther Lake'.
Using regions: "bios", "fd".
Reading flash... done.
SUCCESS

85b977151b ichspi.c: Add support for region 9 and beyond in Meteor Lake
Since Meteor Lake, configuring region access for FREG9 and higher is
necessary. This configuration is determined using BIOS_BM registers:

BIOS_BM_RAP (Offset 0x118): BIOS Master Read Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master read access.

BIOS_BM_WAP (Offset 0x11c): BIOS Master Write Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master write/erase access.

Move CHIPSET_METEOR_LAKE to the bottom of the ich_chipset list to ensure
that all the newer chipsets in the future will use BIOS_BM check by
default.

183208b5cb udelay: only use OS time for delays, except on DOS
As proposed on the mailing list ("RFC: remove the calibrated delay
loop" [1]), this removes the calibrated delay loop and uses OS-based
timing functions for all delays because the calibrated delay loop can
delay for shorter times than intended.

When sleeping this now uses nanosleep() unconditionally, since usleep
was only used on DOS (where DJGPP lacks nanosleep).  When busy-looping,
it uses clock_gettime() with CLOCK_MONOTONIC or CLOCK_REALTIME depending
on availability, and gettimeofday() otherwise.

The calibrated delay loop is retained for DOS only, because timer
resolution on DJGPP is only about 50 milliseconds. Since typical delays
in flashrom are around 10 microseconds, using OS timing there would
regress performance by around 500x. The old implementation is reused
with some branches removed based on the knowledge that timer resolution
will not be better than about 50 milliseconds.

Tested by reading and writing flash on several Intel and AMD systems:

 * Lenovo P920 (Intel C620, read/verify only)
 * "nissa" chromebook (Intel Alder Lake-N)
 * "zork" chromebook (AMD Zen+)

1dd7c88f41 ichspi: Add support for C740 PCH
Clean commit 51e1d0e4b7670e5822560acc724a6a8dd00b6af4
'Add support for Intel Emmitsburg PCH' which broke
CHIPSET_5_SERIES_IBEX_PEAK detection and which assumes C740 is the same
as C620, while its more a close relative to Intel's H570 PCH.

Based on Intel SPI Programming Guide #619386.

Test: Run on Intel ArcherCity CRB with Intel's C741 PCH
      using the 'internal' programmer.
Test: Run on BMC and accessed the SPI flash chip over
      'linux_mtd' programmer.

f15e6a105b programmer: Use correct type for flashbase
The flashbase is a machine-sized integer representation of
address space and so use the appropriate type that is correctly
sized to encode such data.

The flashbase is assigned to 'base' in 'map_flash()' and the
type correctly changed to uintptr_t in commit 4e32ec19b124a7
therefore makes for a consistent type usage whenever stored.

While `sizeof(unsigned long)` and `sizeof(uintptr_t)` are both `8` under
most circumstances on a 64bit platform and thus have enough bits to
represent all addresses on the platform, the C standard does not
guarantee this. Only `uintptr_t` and `void *` has a guaranteed
isomorphism as `uintptr_t` is defined by the platforms toolchain support
whereas the conversion from `void *` to an integer is implementation
defined and that the memory address value may contain additional bits
describing the validation data or provenance of the address. Therefore a
integer is insufficient to contain all the necessary information for
that specific platform so this may not always work out for all platforms
and toolchain combinations.

67b5526d5c internal: Move laptop_ok into board_cfg
Due to how internal is structured around chipset_flash_enable()
entry we need to prepare a crafted programmer_cfg that contains
a board_enable substructure with data derived from the board_enable
subsystem. While this is certainly not perfection, it does make
clear the relationships between board_enable into chipset_flash_enable
and subsequently the overall internal programmer initialisation
in a RAII fashion at the type level over closure upon global
state that is impossible to reason about.

Also flip predicate in report_nonwl_laptop_detected() and
return early with the trivial base-case.

TEST=`$ sudo ./flashrom -p internal --flash-name`.

For example, a programmer such as internal may need to be configured
either as laptop or not type and as such the board enable needs the
ability to feed state back into the programmer configuration. Plumb
this though by creating a board_cfg structure that can be packed.

c66d2bd1ca spi: Make default cmd helpers static internal
Avoid these leaking into driver implementations as a NULL
field now implies their implementation. This removes one
source of a driver bug where both `mst->command` AND
`mst->multicommand` are set to default implementations
which is actually a cyclical control flow condition.

The driver however must still have either `mst->command` OR
`mst->multicommand` defined and so both cannot be NULL.

This simplifies the code and driver development.

0facf12ca4 ch347_spi: Add initial support for the WCH CH347
Add support for the WCH CH347, a high-speed USB to bus converter
supporting multiple protocols interfaces including SPI. Currently only
mode 1 (vendor defined communication interface) is supported, mode 2
(USB HID communication interface) support will be added later. The code
is currently hard coded to use CS1 and a SPI clock of 15 MHz, though
there are 2 CS lines and 6 other GPIO lines available, as well as a
configurable clock divisor for up to 60MHz operation. Support for these
will be exposed through programmer parameters in later commits.

This currently uses the synchronous libusb API. Performance seems to be
alright so far, if it becomes an issue I may switch to the asynchronous
API.

e31d721469 tree/: Make probe_opcode() flashctx argument const
Probing an opcode generally shouldn't involve mutating the flashctx
state and currently no probe_opcode functions do that.

Make the flashctx arg const so that call sites don't need to have a
non-const pointer.

5afd4aeece drivers: Move (un)map_flash_region to par/spi/opaque_master
Move (un)map_flash_region function pointers from programmer_entry to
par_master, spi_master, and opaque_master.  This enables programmers to
specify a different mapper per bus, which is needed for the internal
programmer.  Mapping is closely tied to the way the memory is accessed
using the other functions in the bus master structs.

Validate that FWH/LPC programmers provide specialized mapping in
register_par_master(); this is needed for chips with
FEATURE_REGISTERMAP, which only exist on FWH or LPC buses.

programmer.c: Update comment in fallback_map(), NULL return is the
desired behavior.

Test: Read firmware on SB600 Promontory mainboard (requires physmap)
Test: Read firmware externally with ft2232_spi
Test: Read firmware on ICH hwseq, verify physmap still occurs
