This allows flashrom to identify, read, write, erase and verify flash chips
on (some) 3COM network cards. The patch uses the external programmer
infrastructure, the network card is basically treated as an external
flash programmer.

Usage:

$ ./flashrom -p nic3com
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
No operations were specified.

$ ./flashrom -p nic3com -E
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Erasing flash chip... SUCCESS.

$ ./flashrom -p nic3com -wv backup.bin
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Flash image seems to be a legacy BIOS. Disabling checks.
Programming page: 1023 at address: 0x0000ffc0
Verifying flash... VERIFIED.

$ ./flashrom -p nic3com -r backup.bin
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Reading flash... done.

I have tested this on actual hardware (see PCI IDs above) and all
operations worked fine.

Support for other 3COM cards will follow (I added some more which should
be supportable by this code, but they're untested so far), as well as
support for NICs from other vendors.

The patch also adds support for the Atmel AT49BV512 which is soldered
onto the 3COM NIC I used for testing.

- Read/write accesses through function pointers
- Command line parameter for internal/external flasher
- Board and chipset setup moved to internal init function
- Shutdown stuff moved to internal shutdown function

As a side benefit, this will allow us to undo chipset write enable
during shutdown.

The old variant of using &>/dev/null works on bash and zsh, but not on
dash and tcsh. dash and tcsh interpret it as "background command and
truncate /dev/null" which is not what we want. >& works on tcsh and
bash, but it is not POSIX compliant.
Since make uses /bin/sh and /bin/sh has to be POSIX compliant, we can
use the POSIX variant of stderr and stdout redirection.

>/dev/null 2>&1
is POSIX compliant. This is specified in SuSv3, Shell Command Language,
sections 2.7.2 and 2.7.6.

Jedec subroutines 'probe_jedec()' and 'erase_chip_jedec()'

needed due to a byte wise writing mechanism for this chip.

DOC support has been disabled by default for many years. The write function
does nothing but print text. It has a call to write_page_md2802() commented
out, but that function does not exist. This is dead code with ugly #ifdefs.

didn't work. Removes M-Systems #defines and also includes svn rm msys_doc.*

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

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.

The SPI chip finding and SPI chip accessor code is moved as well. This
can be split later if we feel like it.

The non-use of svn cp is intentional because the only history we'd
have to preserve are a few commits which were early prototypes of chip
identification code. For those who intend to look at that history, they
can look at board_enable.c revision 2853.

This splits up the ROM Write enable code into chipset specific and
board specific parts. This of course means that a lot of code is
plainly moved about.

* Allows for linuxbios name matching and pci-subsystem id matching.
  The latter uses a double set to properly distuinguish boards despite
  of some known vendors being lax about it.
* Fixes GPIO15 being raised on every VT8235 southbridge, regardless of what
  that line actually controls; rom on EPIA-M, backlight on mitac 8999 laptop.
* Adds flashrom support for Asus A7V400-MX (KM400 + VT8235)
* Island aruma was renamed agami aruma, the board specific code now got
  adjusted. A set of pci-ids was retrieved from source code.
