The ChromiumOS flashrom fork has since const'ify flashctx
in a few places. This aligns the function signatures to
match with downstream to ease forward porting patches
out of downstream back into mainline flashrom.
This patch is minimum viable alignment and so feedback is
welcome.

The raiden_debug programmer is of type USB. However, it does not set the
field `devs.dev`, which will result in a segfault when trying to print
the devices of the non-existing table.
Fix that by replacing `devs.note` with `devs.dev` and adding an empty
device table. Since Device IDs are not used to match programmers,
nothing could be added to the table.
TEST=Running `flashrom -L` no longer segfaults and returns normally.

We used to bail out on any unknown laptop. However, modern systems with
SPI flashes don't suffer from the original problem. Even if a flash chip
is shared with the EC, the latter has to expect the host to send regular
JEDEC SPI commands any time.
So instead of bailing out, we limit the set of buses to probe. If we
suspect to be running on a laptop, we only allow probing of SPI and
opaque programmers. The user can still use the existing force options
to probe all buses.
This will obsolete some board-enables that could be moved to `print.c`
in follow-up commits.

The 96Boards Developerbox (a.k.a. Synquacer E-series) provides a CP2102
debug UART with its GPIO pins hooked up to the SPI NOR FLASH. The
circuit is intended to provide emergency recovery functions without
requiring any additional tools (such as a JTAG or SPI programmer). This
was expected to be very slow (and it is) but CP2102 is much cheaper than
a full dual channel USB comms chip.
Read performance is roughly on par with a 2400 baud modem (between 60
and 70 minutes per megabyte if you prefer) and write performance is 50%
slower still. The full recovery process, with backup and verification of
4MB data written takes between 14 and 15 hours. Thus it is only really
practical as an emergency recovery tool, firmware developers will need
to use an alternative programmer.

On systems where the overhead of getting/setting pins is much greater
than the half period (for example, USB bit banging) it significantly
boosts performance if we can bang more than one bit at the same time.
Add support for setting sck at the same time as mosi or miso activity.
The speed up varies depending on how much the overhead of
getting/setting pins dominates execution time. For a USB bit bang driver
running on a 7th generation Core i5, the time to probe drops from ~9.2
seconds to ~7.7 seconds when set_clk_set_mosi() is implemented.

Tested to work read/write/erase with "-p digilent_spi -c M25P10" or
with a patch that resets the part beforehands (in which case it gets
detected as a M25P10-A and is way faster due to paged writes).

This imports a series of patches from chromiumos for MTD support.
The patches are squashed to ease review and original Change-Ids have
been removed to avoid confusing Gerrit.
There are a few changes to integrate the code:
- Conflict resolution
- Makefile changes
- Remove file library usage from linux_mtd. We may revisit this and use
it for other Linux interfaces later on.
- Switch to using file stream functions for reads and writes.

linux_mtd: do reads in eraseblock-sized chunks
It's probably not the best idea to try to do an 8MB read in one syscall.
Theoretically, this should work; but MTD just relies on the SPI driver
to deliver the whole read in one transfer, and many SPI drivers haven't
been tested well with large transfer sizes.
I'd consider this a workaround, but it's still good to have IMO.

This is the 6th commit message:
linux_mtd: make read/write loop chunks consistent, and documented
Theoretically, there should be no maximum size for the read() and
write() syscalls on an MTD (well, except for the size of the entire
device). But practical concerns (i.e., bugs) have meant we don't quite
do this.
For reads:
Bug https://b/35573113 shows that some SPI-based MTD drivers don't yet
handle very large transactions. So we artificially limit this to
block-sized chunks.
For writes:
It's not clear there is a hard limit. Some drivers will already split
large writes into smaller chunks automatically. Others don't do any
splitting. At any rate, using *small* chunks can actually be a problem
for some devices (b:35104688), as they get worse performance (doing an
internal read/modify/write). This could be fixed in other ways by
advertizing their true "write chunk size" to user space somehow, but
this isn't so easy.
As a simpler fix, we can just increase the loop increment to match the
read loop. Per David, the original implementation (looping over page
chunks) was just being paranoid.
So this patch:
* clarifies comments in linux_mtd_read(), to note that the chunking is
somewhat of a hack that ideally can be fixed (with bug reference)
* simplifies the linux_mtd_write() looping to match the structure in
linux_mtd_read(), including dropping several unnecessary seeks, and
correcting the error messages (they referred to "reads" and had the
wrong parameters)
* change linux_mtd_write() to align its chunks to eraseblocks, not page
sizes
Note that the "->page_size" parameter is still somewhat ill-defined, and
only set by the upper layers for "opaque" flash. And it's not actually
used in this driver now. If we could figure out what we really want to
use it for, then we could try to set it appropriately.

This patch sets the default baud rate for communication between
the host device and the Bus Pirate for hardware versions 3.0
and greater to 2M baud.
It also introduces the ability to manually set the baud rate via
the added 'serialspeed' programmer parameter.
This is done in two parts. Firstly, the requested serial speed is looked up
in a table to determine the appropriate clock divisor and the divisor is sent
to the bus pirate. Then, the system's baud rate for the selected serial port
is set using serial.c's 'serialport_config'. This function's prototype had to
be added to programmer.h.
In testing, using the 2M baud rate was able to significantly decrease
flash times (down from 20+ minutes to less than 2 minutes for an 8MB flash).

Add a feature flag SPI_MASTER_4BA to `struct spi_master` that advertises
programmer-side support for 4-byte addresses in generic commands (and
read/write commands if the master uses the default implementations). Set
it for all masters that handle commands address-agnostic.
Don't prefer native 4BA instructions if the master doesn't support them.

Get rid of the layering violations around ICH's BBAR. Move all the weird
address handling into (surprise, surprise) `ichspi.c`. Might fix writes
for the `BBAR != 0` case by accident.
Background: Some ICHs have a BBAR (BIOS Base Address Configuration
Register) that, if set, limits the valid address range to [BBAR, 2^24).
Current code lifted addresses for REMS, RES and READ operations by BBAR,
now we do it for all addresses in ichspi. Special care has to be taken
if the BBAR is not aligned by the flash chip's size. In this case, the
lower part of the chip (from BBAR aligned down, up to BBAR) is inacces-
sible (this seems to be the original intend behind BBAR) and has to be
left out in the address offset calculation.

This adds PCI IDs for C620-series PCHs and adds
CHIPSET_C620_SERIES_LEWISBURG as a new entry in the ich_chipset enum.
Lewisburg is very similar to Sunrise Point for Flashrom's purposes,
however one important difference is the way the "number of masters" is
interpreted from the flash descriptor (0-based vs. 1-based). There are
also new flash regions defined.

The pci_dev structure is never meant to be used as is, but always as a
pointer. By using the struct itself in undo_pci_write_data, we are risking
data corruption, or buffer overflows if the structure size changes.
This is especially apparent on my system where flashrom segfaults
because I compile it with pciutils 3.3.0 and I run it on a system
with pciutils 3.5.2. The struture size is different and causes a
struct with the wrong size to be sent to the library, with invalid
internal field values.
This has been discovered and discussed in Change ID 18925 [1]

All publicly known Skylake / Kabylake / Sunrise Point PCH variants
share the same register interface [1..6]. Although all SPI configu-
ration is now done through the SPI PCI device 1f.5, we can't probe
for it directly since its PCI vendor and device IDs are usually hid-
den.
To work around the hidden IDs, we use another PCI accessor that doesn't
rely on the OS seeing the PCI device.
This handles SPI flashes only. While booting from LPC is still sup-
ported, it seems nobody uses it any more.
Some additional PCI IDs were gathered from driveridentifier.com.
TEST=Compiled with B150 set to NT (instead of BAD) and checked for
sane register readings.

The subtle difference was ignored when adding these chipsets. The
integrated Wildcat Point LP PCH is documented in [1].
I'm not sure how to account for "Broadwell H" which seems not publicly
documented. Maybe it's an unreleased HM9*, in which case the non-LP
path should be correct.

Supported controllers are Promise PDC20262 (FastTrak66/Ultra66),
PDC20265 (FastTrak100 Lite/Ultra100), PDC20267 (FastTrak100/Ultra100).
At least the Ultra100 only has address lines A0-A14 wired up, limiting
addressable chip size to 32 kB. The flash chips mounted on those
controllers usually is 128 kB, i.e. parts of the flash chip are
inaccessible. As a workaround, the driver implicitly truncates the
size of all flash chips to 32 kB. Works well for the factory installed
flash.
Do NOT use as a generic programmer for chips >32 kB.

The serprog protocol does only transmit 24 bit-wide address and ignores the
top 8 bit. This is fine as long as the underlying hardware ignores the latter
anyway (which is the case for parallel chips that even lack the respective pins).
FWH/LPC chips, however, operate on a full 32-bit (LPC) or 28-bit (FWH) address
space and would fail with the fallback mapping to NULL.

This patch was inspired by the code in AVRDude (open source Atmel AVR

Dediprog code in flashrom was used as the template for this code with
some reference to the ft2232 code as well.

- Fix copy&paste error in spi_prettyprint_status_register_bp().
Spotted by Pablo Cases.
- Add an additional SMBus controller revision to identify another Yangtze
model. Thanks to Dan Christensen for reporting this issue.
- dediprog: add missing include for stdlib.h.
This fixes (at least) building on FreeBSD and DragonflyBSD with gcc.
- Remove references to struct pci_filter from programmer.h.
It is only needed in internal.c where it has a complete type. Having
it in programmer.h provokes a warning by some old versions of gcc.
- Tiny other stuff.

We do CPU architecture checks once for the makefile in arch.h and
once for HW access abstraction in hwaccess.c. This patch unifies
related files so that they can share the checks to improve
maintainability and reduce the chance of inconsistencies.
Furthermore, it refines some of the definitions, which
- adds "support" for AARCH64 and PPC64,
- adds big-endian handling on arm as well as LE handling on PPC64,
- fixes compilation of internal.c on AARCH64 and PPC64.
Additionally, this patch continues to unify all OS checks in
flashrom by adding a new helper macro IS_WINDOWS.
The old header file for architecture checking is renamed to platform.h
to reflect its broader scope and all new macros are add in there.

Basically, among other chips, MSTAR manufactures SoCs that equip TV sets
and computer screens, and it seems that all of their products use the
same in-system programming protocol. Basically, they use the DDC channel
of VGA or DVI connectors, which is actually an I2C bus, to encapsulate
SPI frames (the flash chip is connected to the SoC through an SPI bus).
I wrote this patch since the screen I bought had a software bug, and the
manufacturer only released a new firmware binary, but no tool or
instructions on flashing it.
More details can be found here:
http://boeglin.org/blog/index.php?entry=Flashing-a-BenQ-Z-series-for-free(dom)
I only read code from Linux kernel archives published by Acer to figure
out the protocol (for a touchscreen controller and an NFC chip, both by
MSTAR, that share the same ISP protocol), so I don't think there are
any legal problems with it.
Compilation is currently disabled by default in the Makefile.
If in doubt, additional Makefile bugs were added by Stefan.

The Wildcat Point PCH can be paired with Broadwell or Haswell.
This patch was essentially backported from ChromiumOS commit 9bd2af8.

The core of this patch to support Bay Trail originally came from the
Chromiumos flashrom repo and was modified by Sage to support the
Rangeley/Avoton parts as well.
Because that was not complicated enough already Stefan Tauner refactored
and refined everything. Bay Trail seems to be the first Atom SoC able to
support hwseq. No SPI Programming Guide could be obtained so it is
handled similarly to Lynx Point which seems to be its nearest relative.

- Change check_max_decode() to return the number of (common) busses
where the flash chip exceeds the supported size of the programmer.
- Refine its signature to use a flashctx pointer only.
- Move CLI-related bits to cli_classic.c.
- Rename check_max_decode() to count_max_decode_exceedings() to
better reflect what it (now) really does.
- Refine the messages printed by the caller to better integrate with the new
setup, and simplify them.

Begin to move functions that clearly belong to the (command line)
user interface out of flashrom's core files like flashrom.c.
- Refine messages within check_chip_supported(), rename it to
print_chip_support_status() and move it to newly created cli_common.c.
- Move flashbuses_to_text() to cli_common.c as well.
- Move global verbosity variables to cli_output.c.

This patch lets you read and write the EEPROM on 82580-based gigabit NIC
cards. So far it has been tested on copper NICs only, but other variants
employing this controller should work too.
It is a nice substitution for the official eeupdate tool.
Speed is quite decent: less than 4 seconds for erases or writes of 32 kB.
