W39V040C does standard JEDEC commands except chip erase so add a small driver.
probe_w39v040c() prints the block lock pin status when a chip is found.

The Neo2 board enable matches on 8237-internal IDE and onboard NIC PCI IDs.

Many thanks to Daniel McLellan for testing all of this on hardware!

This patch adds support to the AMIC A29002 chip in its top and bottom
configuration to flashrom. Additionally, the alphabetic order of the
AMIC chips was fixed.

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
mx29f002 driver, which does chip erase before writing, rather than am29f040b,
which uses sector erase.

which is only needed when running coreboot, that slipped in the original
commit and through the original review ;-) So it must be trivial enough.

DOC support has been disabled by default for many years. The write function
does nothing but print text. It has a call to write_page_md2802() commented
out, but that function does not exist. This is dead code with ugly #ifdefs.

Updates README to reflect that there was a time when there was code, but it
didn't work. Removes M-Systems #defines and also includes svn rm msys_doc.*

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.

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.

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

Add support for the JEDEC RES (Read Electronic Signature and Resume from
Powerdown) SPI command 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.
