Peter Stuge d1f698ac27 flashrom: Board enable and autodetection for BioStar P4M80-M4.
Thanks to Reinder for clean room reverse engineering and data sheet diving!

This board is autodetected because there are some good BioStar subsystem IDs.
Matching uses onboard VT6420 SATA RAID with subsystem BioStar 3206 and
onboard UniChrome Pro IGP graphics with subsystem BioStar 1202.

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.

Tested on actual hardware.

This patch add an ich_gpio_raise() function which can be re-used by other
board-specific funtions which need to raise GPIOs on ICHx southbridges.

This also fixes bug #7, see http://tracker.coreboot.org/trac/coreboot/ticket/7,

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

Thanks go to Nikolay for this patch.

Carl-Daniel Hailfinger fb047a6a54 I looked at the datasheet and erase_sector_39sf020() is totally and
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.

For this reason, ST M50FLW support is moved to a

would bear the risk to cause problems with the already
supported devices.

It's already tested with ST M50FLW080A; the other

Claus Gindhart 20ba8eb7ab Flash pages, which where excluded from updating using the exclude or the
layout option, as well as areas, whose flash contents already contain the
desired data, will be skipped.
These ensures absolute data security of critical areas (BIOS boot block), 
e.g. against a sudden power off or a CPU hangup during flashing. As a
nice side effect, it speeds up the flash process, if the BIOS to be flashed
is very similar to the version in flash.

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.

Carl-Daniel Hailfinger 6d6146c377 Fix ATMEL 29C020 detection with flashrom. The JEDEC probe routine had
a delay of 10 us after entering ID mode and this was insufficient for
the 29C020. The data sheet claims we have to wait 10 ms, but tests have
shown that 20 us suffice. Allow for variations in chip delays with a
factor of 2 safety margin.
