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,
as it turned out the ICH2 (and other ICHx) code works fine.

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

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.

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.

Currently there is an ongoing technology migration from LPC/FWH to SPI chips.
For this reason some boards have multiple chips of different technologies
onboard. This patch makes flashrom probe for up to 3 chips and if more than
one chip is found flashrom exits, asking the user to specify -c.
[root@localhost src]# ./flashrom
...
Multiple flash chips were detected: SST49LF008A M25P16@ICH9
Please specify which chip to use with the -c <chipname> option.

8 bits out of 32 are in use now. No bits set means nothing has been tested.
For chips with at least one operation that is not tested or not working, the
user is asked to email a report to a special email adress so that the table
can be updated.
All chips are TEST_UNTESTED for now.

The generic jedec.c does not work for the ST M50FLW flash devices,
because they need an unlock command first. For this reason, ST M50FLW
support is moved to a new HW support module, because any change in
jedec.c would bear the risk to cause problems with the already supported
devices.
It's already tested with ST M50FLW080A; the other chips of this family i
dont have available, so i couldnt test it.

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.
