flashrom. Not all chips support all commands, so allow the implementer
to select the matching function.
Fix a layering violation in ICH SPI code to be less bad. Still not
perfect, but the new code is shorter, more generic and
architecturally
more sound.
TODO (in a separate patch):
- move the generic sector erase code to spi.c
- decide which erase command to use based on info about the chip
- create a generic spi_erase_all_sectors function which calls the
generic sector erase function
Thanks to Stefan for reviewing and commenting.

They all use a different init sequence than the more modern ITE Super I/Os.
For now we only use 0x370 as config port, but 0x3f0 or 0x3bd would also be
valid. Contrary to other Super I/Os, the config port for these is _not_
hardcoded via hardware, instead it can be programmed by software, i.e.
you get to choose whether you want to use 0x370, 0x3f0, or 0x3bd.

specification and local testing.
Also tweak a little bit algorithm for (internal) device ID calculation:
Chips from the W83627HF/F/HG/G family have an ID of 0x52 and a multitude of
revisions (0x1x, 0x3a, 0x41, maybe more), chips from the W83627HF/GF family
have the same device ID but revisions 0xfx.
Please note that the last line of the patch simply fixes the comment
about internal device ID composition (upper half of reg 0x21 is used).
I chose the most conservative way of detecting W83627HF - only if reg
0x21 value matches 0xFx we skip the previous logic and keep using it for
all other revisions.

the true positive match in case there is more than one flash chip and the 2nd

While writing a new SPI driver I fixed some things in the SPI code:
All calls to spi_command() had unneccessary #define duplications, and in some
cases the read count define could theoretically become harmful because NULL was
passed for the read buffer. Avoid a crash, should someone change the #defines.
I also noticed that the only caller of spi_page_program() was the it87 driver,
and spi_page_program() could only call back into the it87 driver. Removed the
function for easier-to-follow code and made it8716f_spi_page_program() static.
The ichspi driver's static page functions are already static.

Preparation for a probe optimization patch. This patch does not change any
functionality. spi_probe_rdid was tested to still work on my M57SLI rev 2.
The idea is to have error checks return error immediately when something
fails, rather than having code inside an if block where the condition
tests for success.
This means: Less indentation, more clear what the code is checking.

Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
using _jedec and _49lf040 functions.
An issue was found with probe_w29ee011() for the Winbond W29EE011, which
caused the A49LF040A to no longer respond to any commands.
Ward made a patch to disable probing by default for the W29EE011 following
some discussion. Using -c W29EE011 will make flashrom probe for the chip.
Peter did some more datasheet diving and found that the Pm49FL00x functions
suited this chip quite well because of the block locking registers in
A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.
Ward confirmed that this works on alix.2c3 too.

When flash chip detection fails, it is still useful and possible to read the
flash chip contents. If no flash chip is found in normal probes and the
-f -r -c CHIPNAME options are given, a successful probe for the specified
chip is forced, and then flashrom reads the flash chip using either the read
function for the specified chip, or if there is none, a simple memcpy().
The patch also moves the global variable int force in flashrom.c into main()
and passes it as a parameter to layout.c:show_id(), which was the only other
function that used the variable. This is needed to avoid confusion with the
new parameter int force which is added to flashrom.c:probe_flash() and used
to force probe success for the chip named in char *chip_to_probe.

SST SST49LF160C is confirmed to work for PROBE READ ERASE WRITE, at least on
2 MCP55-based boards (gigabyte m57sli v1 and supermicro h8dmr).
On the m57sli board, it only works > 512K when booted into coreboot; the
proprietary bios seems to do something weird where it locks rom access down
to the first 512K of the chip.
