There are multiple albatron pm266a boards which all share the same bios
image. This means that both the board enable and the subsystem ids are
exactly the same.

The board enable is the same as the epox EP-8K5A2, namely only raising
memw on the superio.

Add chip_{read,write}n to the external flasher infrastructure which
read/write n bytes at once.

Fix a few places where the code used memcpy/memcmp although that is
strictly impossible with external flashers.
Place a FIXME in the layout.c code because usage is not totally clear
and needs to be fixed to support external flashers.

As a nice side benefit, we get a noticeable speedup for builtin flash
reading which is now a memcpy() of the full flash area instead of a
series of single-byte reads.

It doesn't make sense to probe for SPI chips on a LPC host, nor does it
make sense to probe for LPC chips on a Parallel host.

This change is backwards compatible, but adding host protocol info to
chipset init functions will speed up probing.

Once all chipset init functions are updated and the Winbond W29EE011 and
AMIC A49LF040A chip definitions are updated, the W29EE011 workaround can
be deleted as the W29/A49 conflict magically disappears.

Right now, the annotation only differentiates between SPI and non-SPI.
Anyone who knows more about a specific flash chip should feel free to
update it.

The existing flashbus variable was abused to denote the SPI controller
type. Use an aptly named variable for that purpose.

Once this patch is merged, the chipset/programmer init functions can set
supported flash chip types and flashrom can automatically select only
matching probe/read/erase/write functions. A side benefit of that will
be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict.

Every chip besides SPI and w39v080fa uses id1/id2 as local variable
names to store ID responses from the flash chip. This eases grepping a
lot. As a bonus, it also frees up some names to be used as parameters.

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.
