Downgrade the chips from 256-byte writes to 1-byte writes. This fixes
writing to them on ICH/VIA SPI masters.

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.

Flashrom assumes that the flash chip contents are available via mmap if
no read function is defined.

This special case is handled in lots of places all over the code.

Remove the special case and use the read_memmapped function. Not only
does this allow us to fix a read bug in flashrom I recently uncovered on
ICH SPI, it also allows us to add support for Paraflasher to flashrom.

That is incorrect.

A bit of confusion comes from how the #defines are named. We call them
TEST_BAD_*, but the message printed by flashrom says: "This flash part
has status NOT WORKING for operations:"

Something that is unimplemented is definitely not working.

Neither of the chip entries mentioned above has erase or write functions
implemented, so erase and write are not working. Since their size is
unknown, we can't read them in. That means read is not working as well.
Probing is a different matter. If a chip-specific probe function had
matched, we wouldn't have to handle the chip with the "unknown xy SPI
chip" fallback. I'm tempted to call that "not working" as well, but I'm
open to discussion on this point.
