Fully tested for Probe/Read/Erase/Write on EN29F002NT.
Jedec subroutines 'probe_jedec()' and 'erase_chip_jedec()'
are still in use, but a tailored 'write_en29f002a()' is
needed due to a byte wise writing mechanism for this chip.

Thanks to Mats for the initial idea and implementation of a tool to do
this. This patch has almost the same behaviour as the original tool
without having to run the tool each time.
Tested for abuild-friendliness.
The patch saves ~10-12 seconds for every target using romcc. For a full

For the first 38 abuild targets, total build time is down to 13m24s
instead of 16m22s on my machine.

This removes the false positive matches we've been seeing, and also removes
the true positive match in case there is more than one flash chip and the 2nd
or 3rd are unknown - but I think that case is uncommon enough to warrant the
improvement in the common case. Use flashrom -frc forced read if you have the
uncommon case, and/or please add the flash chip to the flashchips array.

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.

The datasheet is at <http://www.amictechnology.com/pdf/A29002.pdf>.
A29002T PREW functionality was tested and works.
This flash chip has asymmetric sector layout so it is important to use the

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

tests for success.

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.

This patch addresses different argument order of outX() calls,
FreeBSD-specific headers, difference in certain type names and system
interface names, and also FreeBSD-specific way of gaining IO port
access.

The PMC chips understand both LPC and FWH flash commands. When in FWH mode
(MSR_DIVIL_BALL_OPT(0x51400015) = 0x00000f7d on 5536 boards) the Block
Locking Registers by default lock the flash chip for write and erase - in
addition to any chipset write protection.
This patch adds unlock operations before Pm49FL004/2 write and erase, and
it includes an svn mv pm49fl004.c pm49fl00x.c
Thanks go to Nikolay for this patch.

completely wrong. It was a straight cut'n'paste from SST 28SF040 code
and the person doing the cut'n'paste didn't even bother to check the
data sheet. The SST 39SF020 is completely incompatible with the 28SF040.
No need for replacement. According to the data sheet, standard JEDEC
commands will work and we have those commands in the tree already.

Powerdown) SPI command to flashrom to identify older SPI chips which
can't handle JEDEC RDID. Since RES gives a one-byte identifier which is
shared among many different vendors and even different sizes, we want to
match RES as a last resort if RDID returns 0xff 0xff 0xff.
