The device id for Am29DL800BB in jedec_probe.c is wrong.
Reference: http://www.spansion.com/datasheets/21519c4.pdf
I discovered this while working with u-boot.
The u-boot folks mentioned Linux as an upstream reference, thought I'd
post a heads-up here too.

The unlock_addr rework in kernel 2.6.25 breaks 16-bit SST chips. SST
39LF160 and SST 39VF1601 are both 16-bit only chip (do not have BYTE#
pin) and new uaddr value is not correct for them. Add
MTD_UADDR_0xAAAA_0x5555 for those chips. Tested with SST 39VF1601
chip.

Once upon a time, the MTD repository was using CVS.
This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.
This also includes code that printed them to the user.

This patch add support for non-CFI Eon EN29SL800B[BT] NOR flash chips.
The Eon chips have manufacturer ID in the first bank, therefore this patch
depends on support for flash chips with ID in bank other than 0.

According to JEDEC "Standard Manufacturer's Identification Code"
(http://www.jedec.org/download/search/jep106W.pdf)
several first banks of NOR flash can contain 0x7f instead of actual ID.
This patch adds support for reading manufacturer ID from banks other than 0.

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.

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!
