e4e3295f0c Revert "[MTD] blkdev helper code: fix printk format warning"
This reverts commit 668040fcd1.

The 'flags' field of the struct request is 'unsigned long'. Quite
how Randy came to see 'long int format, different type arg' I don't
know, but it doesn't seem to be the case any more.

e417fcfb85 [MTD] Remove iq80310 map driver
The iq80310 mtd map driver depends on ARCH_IQ80310, which isn't
defined anywhere in the tree (as we don't have 80310 support), and
furthermore, everything the driver does can be done with physmap
instead.

25f0c659fe ioremap balanced with iounmap for drivers/mtd subsystem
ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.

Tested (compilation only) with:
- allmodconfig
- Modifying drivers/mtd/maps/Kconfig and drivers/mtd/nand/Kconfig to
make sure that the changed file is compiling without warning

187ef15268 [MTD] Unlock NOR flash automatically where necessary
Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is
always locked after power-up, so all sectors need to be unlocked before it
is usable.

If this flag is set, and the chip provides an unlock() operation,
mtd_add_device will unlock the whole MTD device if it's writeable.  This
means that non-writeable partitions will stay locked.

Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work
as expected.

de591dacf3 MTD: Fix bug in fixup_convert_atmel_pri
The memset() in fixup_convert_atmel_pri is supposed to zero out
everything except the first 5 bytes in *extp, but it ends up zeroing
out something way outside the struct instead. Fix this potentially
dangerous code by casting the pointer to char * before doing
arithmetic.

0165508c80 MTD: Add lock/unlock operations for Atmel AT49BV6416
The AT49BV6416 is locked by default, so we really need to provide
at least the unlock() operation for write and erase to work. This
patch implements both ->lock() and ->unlock() and provides a fixup
to install them when an AT49BV6416 chip is detected.

These functions are probably valid on more Atmel chips, but I believe
it's mostly obsolete ones. The AT49BV6416 is in fact obsolete, but
it's used on all current AT32STK1000 development boards.

5b0c5c2c0d MTD: Convert Atmel PRI information to AMD format
Atmel flash chips don't have PRI information in the same format as
AMD flash chips. This patch installs a fixup for all Atmel chips that
converts the relevant PRI fields into AMD format.

Only the fields that are actually used by the command set is actually
converted. The rest are initialized to zero (which should be safe)
