For "unlock" cycles to 16bit devices in 8bit compatibility mode we need
to use the byte addresses 0xaaa and 0x555. These effectively match
the word address 0x555 and 0x2aa, except the latter has its low bit set.

Most chips don't care about the value of the 'A-1' pin in x8 mode,
but some -- like the ST M29W320D -- do. So we need to be careful to
set it where appropriate.

cfi_send_gen_cmd is only ever passed addresses where the low byte
is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are
affected by this patch, by masking in the extra low bit when the device
is known to be in compatibility mode.

[dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa]
v4: Fix  stupid typo in cfi_build_cmd_addr that failed to compile
    I'm writing this patch way to late at night.
v3: Bring all of the work back into cfi_build_cmd_addr
    including calling of map_bankwidth(map) and cfi_interleave(cfi)
    So every caller doesn't need to.
v2: Only modified the address if we our device_type is larger than our
    bus width.

I discovered this while working with u-boot.

The u-boot folks mentioned Linux as an upstream reference, thought I'd

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.

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.

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!
