RES is Read Electronic Signature (1 Byte, identical for different chips)
REMS is Read Electronic Manufacturer Signature (2 Bytes, mostly unique)
RDID is Read JEDEC ID (3 bytes, unique)

Of the chips which don't support RDID, a sizable portion supports REMS
which gives us both a manufacturer ID and a device ID. This is clearly
superior to having only a device ID (the RES case) which has multiple
documented collisions.

The RES/REMS problem is aggravated by inconsistent naming in vendor data
sheets. What's in a name? Considering that we have 1-byte IDs, 2-byte
IDs and 3+byte IDs with varying names but mostly consistent opcodes, it
makes sense to set our own standard about how the opcodes are called.

The best way forward would be to have the ICH SPI driver reprogram the
opcode menu on the fly if the opcode menu doesn't contain the requested
opcode and the opcode menu is not locked. Until that happens, this patch
improves detection accuracy by a factor of 256 for some chips.

While the other chipset enables for nvidia could potentially also work,
this one, by not touching other bits, seems like the safest solution.

Uwe tested this on his Asus A7N8X Deluxe, so hopefully the A7N8X-E

I tested identify, read, write, erase, verify successfully, HOWEVER,
this will only work (at least on my card) after de-soldering the
soldered-on PLCC32 one-time programmable (OTP) chip (Holtek HT27C010)
and soldering on a (re-)programmable flash ROM chip or a socket.

Example:

http://www.coreboot.org/File:Sii_controller1.jpg
http://www.coreboot.org/File:Sii_controller2.jpg



The OTP chip which came on my card does not react to the standard JEDEC
identify/read/write/erase commands anymore, so if all other such PCI0680
controllers which are around also have the same OTP chip (that's not
necessarily the case), they cannot be used as "external programmer" in
flashrom without the above mentioned modifications.

Thanks Michael Heimann for reporting.

The board was misidentified as a GIGABYTE GA-MA78G-DS3H though, as the
old PCI IDs and subsystem IDs of match. Thus, use differing ones for
both boards, which is not so easy. The only usable-looking difference
is in the SATA controller subsystem IDs. This should allow us to
properly detect both boards.

Some MMIO accesses used volatile, others didn't (and risked
non-execution of side effects) and even with volatile, some accesses
looked dubious.

Since the MMIO accessor functions and the onboard flash accessor
functions are functionally identical (but have different signatures),
make the flash accessors wrappers for the MMIO accessors.

For some of the conversions, I used Coccinelle. Semantic patch follows:

@@ typedef uint8_t; expression a; volatile uint8_t *b; @@ - b[a] + *(b
+ a) @@ expression a; volatile uint8_t *b; @@ - *(b) |= (a); + *(b) =

Use chipaddr instead of volatile uint8_t * because when we access chips
in external flashers, they are not accessed via pointers at all.

Benefits: This allows us to differentiate between volatile machine
memory accesses and flash chip accesses. It also enforces usage
of chip_{read,write}[bwl] to access flash chips, so nobody will
unintentionally use pointers to access chips anymore. Some unneeded
casts are removed as well. Grepping for chip operations and machine
memory operations doesn't yield any false positives anymore.

Compile tested on 32 bit and 64 bit Linux.

The emulation works by splitting 32 bit accesses into 16 bit accesses
and 16 bit accesses into to 8 bit accesses. That way, external flashers

EEPROMs basically).

Until the ICH SPI driver can handle preopcodes as standalone opcodes,
we should handle such special opcode failure gracefully on ICH and
compatible chipsets.

This fixes status register writes on almost all ICH+VIA SPI masters.

The fix is almost identical to r484, but this time it affects the EWSR
(Enable Write Status Register) opcode instead of the WREN (Write Enable)
opcode.

With the differentiated return codes introduced in r500, the workaround
is more precise this time. The old WREN workaround was updated as well.

If we find multiple ones, abort with a message to the user, suggesting
to use the

  flashrom -p nic3com=bb:dd.f

syntax. If exactly one supported NIC is found, use it. If none is found,
abort with an error.

Print the bb:dd.f numbers for all supported NICs we find, so the user
doesn't have to poke around in lspci output to find the desired bb:dd.f.

Also, drop one pci_read_long() in favor of using the already existing
base_addr[0] struct field.

Drop the BAR in user messages, it's not really useful for us. Instead,
explain the BDF syntax a bit more verbosely.

While I'm at it, update the manpage some more to mention and fully
document the external programmer support we have (or will have soon).
