Carl-Daniel Hailfinger e3da00de8d Lots of new SST flash chip IDs. Only a subset has been added to
flashchips.c, but the IDs in flash.h will make lookups easier if anybody
wants to add support for them.

Carl-Daniel Hailfinger a4868c44b5 Add support for the JEDEC RES (Read Electronic Signature and Resume from
Powerdown) SPI command to flashrom 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.

Carl-Daniel Hailfinger 68db3a2bdc Check the JEDEC vendor ID for correct parity. Flash chips which can be
detected by JEDEC probe routines all have vendor IDs with correct
parity. Use a parity check as additional hint whether a vendor ID makes
sense.
Note: Device IDs have no parity requirements whatsoever.

This paves the way to have a fully generic generic_spi_command without

Claus Gindhart 15da8ed98b flashrom: Probe for up to 3 flash chips.
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.

Claus Gindhart b19973eb8b 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.

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.

Mart Raudsepp 9792a034e4 flashrom: further cleanups to enable_flash_cs5536
- Remove the "enable write to flash" message, as the caller appears to
   already report that.

 - Move the 'modprobe msr' suggestions to the first lseek64 error handling, as
   we get an error there already.

 - Rename a perror string from "read" to "read msr", as we use the latter
   already in this function for another read.

Mart Raudsepp 2995cc69f7 Improve error handling and make RCONF_DEFAULT_MSR address be a constant.
Also, move a big code comment to the top of enable_flash_cs5536().

Mart Raudsepp 99062ae5ad This implements support for devices using AMD Geode companion chip
CS5536 that have the Boot ROM on NOR flash that is directly connected to
FLASH_CS3 (Boot Flash Chip Select).
We need to write enable it in the NORF_CTL MSR register for flashrom to
be able to write to it, including JEDEC probe commands.

This patch allows us to stop using AMD gx_utils.ko for BIOS flashing on
the DBE61.

Carl-Daniel Hailfinger c23b3a5732 Handle JEDEC JEP106W continuation codes in SPI RDID. Some vendors like
Programmable Micro Corp (PMC) need this.
Both the serial and parallel flash JEDEC detection routines would
benefit from a parity/sanity check of the vendor ID. Will do this later.

Add support for the PMC Pm25LV family of SPI flash chips.

Peter Stuge e2bbcb10d1 Make the vendor name optional in the -m flashrom parameter when there's only
one board name that matches. The full syntax still works, and is required
when two vendors have boards with the same names.
