MTD has recently been upgraded for 64-bit support, see commit
number 69423d99fc182a81f3c5db3eb5c140acc6fc64be in the
mtd-2.6.git tree (git://git.infradead.org/mtd-2.6.git)
or see this URL:
http://git.infradead.org/mtd-2.6.git?a=commit;h=69423d99fc182a81f3c5db3eb5c140acc6fc64be
Some variables in MTD data structures which were 32-bit
became 64-bit. Namely, the 'size' field in 'struct mtd_info'
and the 'addr'/'len' fields in 'struct erase_info'. This
means we have to use 'do_div' to divide them.
This patch fixes the following linking error:
ERROR: "__umoddi3" [drivers/mtd/devices/m25p80.ko] undefined!
This patch changes divisions of 64-bit variable so that they use
'do_div'. This patch also change some print placeholders to
get rid of gcc warnings.

* git://git.infradead.org/mtd-2.6:

This fixes broken terminology added in the "m25p80.c erase enhance" patch,
which added a chip erase command but called it "block erase". There are
already two block erase commands; blocks are 4KiB or 32KiB. There's also
a sector erase (usually 64 KiB). Chip erase typically covers Megabytes.
OPCODE_BE ==> OPCODE_CHIP_ERASE
erase_block ==> erase_chip

Commit d0e8c47c58575b9131e786edb488fd029eba443e ("m25p80.c extended jedec
support") added support for extended ids but seems to break on flashes
which don't have an extended id defined. If the table does not have an
extid defined, then we should ignore it.

Commit d0e8c47c58575b9131e786edb488fd029eba443e ("m25p80.c extended jedec
support") added support for extended ids but in the process managed to
break detection of all flashes.
The ext jedec id check was inserted into an if statement that lacked
braces, and it did not add the required braces. As such, the detection
routine always returns the first entry in the SPI flash list.

This reverts commit 75d0ee2202b5740e94e913d8a52f91c6557c4c81.
Although it seems ObviouslyCorrect™, the spi_write() call uses DMA,
while spi_write_then_read() does not. Since our buffer is on the stack,
we must use the latter even though we don't actually want to read
anything back.

This adds a WRITE_VERIFY Kconfig option to the DataFlash driver,
closely mirroring the similar NAND and ONENAND options, giving
an option to disable some code that's currently always enabled.
Removing this step probably saves a millisecond or so per page
when writing data, which will add up quickly since these pages
are small (the largest is 1 KiB). It doesn't seem to add a
lot in terms of reliability, and wouldn't detect errors which
crop up when transferring data to the on-chip SRAM buffer.

Now that we can tell when we have one of the newer DataFlash chips,
optionally expose the 128 bytes of OTP memory they provide. Tested
on at45db642 revision B and D chips.
Switch mtdchar over to a generic HAVE_MTD_OTP flag instead of adding
another #ifdef for each type of chip whose driver has OTP support.

The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:
* Fix the cmdlinepart *regression* that caused testing failures (!!)
by restoring the original part labels in relevant cases.
* Don't reference things that don't exist (!)
- An opcode that doesn't even exist for DataFlash
- The part is "at45db642" not "at45db641"
- ID zero in this JEDEC table
* Make the JEDEC probe routine report and handle errors better:
- If the SPI calls fail, return the error codes.
- Don't depend on ordering of table entries.
- Unrecognized ids are different from parts that have no ID.
We won't actually know how to handle them correctly; display
the ID and ignore the chip.
* Move the original block comment about the "legacy" chip ID scheme
back next to the code to which it applies ... not next to the new
JEDEC query code, which uses an entirely different strategy.
* Don't print a guessed erasesize; /proc/mtd has the real value.
And add a few more comments.

Such a hardcoded address can cause a checkstop or machine check if
the driver is in the kernel but the address is not acknowledged.
Both drivers allow an address to be specified as either a module
parameter or config option. Any future powerpc board should either
use one of these methods or find the address in the device tree.

I have been prime author and maintainer of block2mtd from day one, but
neither MAINTAINERS nor the module source makes this fact clear. And while
I'm at it, update my email addresses tree-wide, as the old address
currently bounces and change my name to "joern" as unicode will likely
continue to cause trouble until the end of this century.

This reverts commit 340ea370c2ce89d1c15fbf785460f2f74314ce58.
It's not needed given the other m25p80 patch (which now handles
at26 "dataflash" as well as most other standard SPI flash chips),
and requires a controller driver that won't be merged upstream
(supplanted by drivers/spi/atmel_spi.c) ... the submitter of
that at91_dataflash26.c driver concurred.
