Use a single unlock address, adjust it for the device type in the
knowledge that it'll be adjusted back again. This has the desirable
effect of masking out the least significant bit of the address for x16
devices.

Having laid the code out so that it's easier to read instead of sticking
to the 80-column guideline even when it doesn't make sense, a bug is
immediately spotted... we were only checking _one_ of the unlock
addresses to see if it runs off the end of the map.

This should have no functional effects -- we've been ignoring all but
the first address in the array for a long time, and using it only to
indicate which device types are supported.

Add descriptions for Fujitsu MBM29F800BA and ST M29F800AB flash chips.
Those chips are compatible (except for the ids) with the AMD AM29F800BB.

This adds flash chip used in Sharp Zaurus sl5500 (collie) to jedec_probe.
Values work for read-only access, but I have not figured out how to do
read-write.

The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.

The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)

This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
