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.

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.

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.
