Mats Erik Andersson ad9bdb4345 Activate proper support for EN29F002(A)(N)[BT].
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.

Peter Stuge ec9e6e33a4 flashrom: Winbond W39V040C and MSI K8T Neo2-F
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!
Build tested by Uwe.

Peter Stuge a4793182e8 flashrom: Trivial SPI cleanups
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.

Carl-Daniel Hailfinger 5bc95858d5 r3415 removed symbolic constants for device IDs by accident.
flash.h is a database of known IDs, whereas flashchips.c is a database
of chips for which support has been implemented. Keep it that way.

Andreas Thienemann ce17f6bdb0 flashrom: Add AMIC A29002
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.

Stefan Reinauer d9b7ae8bec First attempt to clean up SPI probing and create a common
construct: the flash bus.

At some point the flash bus will be part of struct flashchip.

Pardon me for pushing this in, but I think it is important to beware of further
decay and it will improve things for other developers in the short run.

Carl-Daniel, I will consider your suggestions in another patch. I want to keep
things from getting too much for now. The patch includes Rudolf's VIA SPI
changes though.

Jens Kuehnel 42b127fe22 flashrom: Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore
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.

Peter Stuge 646eb245e6 flashrom: Force read unknown flash chips
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.

Nikolay Petukhov ce1fb9d4e9 flashrom: Support Pm49FL004/2 Block Locking Registers
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

Carl-Daniel Hailfinger 717f66d1eb Unfortunately, EN29F002T, EN29F002AT, EN29F002ANT, EN29F002NT all have
exactly the same ID. Improve model number printing.

Add EN29F002(A)(N)B support while I'm at it.

Carl-Daniel Hailfinger 85acc09786 Add continuation ID support to jedec.c
The continuation ID code does not go further than checking for IDs of
the type 0x7fXX, but does this for vendor and product ID. The current
published JEDEC spec has a list where the largest vendor ID is 7 bytes
long, but all leading bytes are 0x7f. The list will grow in the future,
and using a 64bit variable will not be enough anymore.
Besides that, it seems that the location of the ID byte after the first
continuation ID byte is very vendor specific, so we may have to revisit
that code some time in the future.

(Suggestion for a new encoding:
Use a two-byte data type for the ID, the lower byte contains the only
non-0x7f byte, the upper byte contains the number of 0x7f bytes used as
prefix, which is the bank number minus 1 the vendor ID appears in.)

Add support for EON EN29F002AT.

Carl-Daniel Hailfinger 1704179acd This fixes a few vendor IDs to conform with JEDEC publication 106W
(JEP106W), adds some device IDs and provides information about
non-conforming IDs.
The EON change is left to the patch adding EON chips.

This patch should have no effect on code generation.

Carl-Daniel Hailfinger 12a3f1edec To make it easier to add new SPI chips to flashchips.c, rename functions
with multiple possible opcodes from linear numbering at the end (_1, _2)
to include the opcode at the end (_60, _c7). That way, you only have to
take a short look at the data sheet and choose the right function by
appending the opcode listed in the data sheet.
No functional changes.

So I created a very quick patch (attached).
