This reverts commit 668040fcd1e06fc3e68a92708cbdfa5a52c37d3c.
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.

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.

We certainly don't need the check for Linux version > 2.5.2, and in fact
we can also live without the __ECOS check, since we can just add it back
in the eCos git tree which is automatically derived from the Linux fs/jffs2
subdirectory in the upstream git tree.

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.

This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and
40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the
MMIO accesses for PCI config cycles even without the area being marked
reserved in the e820 memory tables.
Those changes were needed for EFI-environment Intel macs, but broke some
newer Intel 965 boards, so for now it's better to revert to our old
2.6.17 behaviour and at least avoid introducing any new breakage.
Andi Kleen has a set of patches that work with both EFI and the broken
Intel 965 boards, which will be applied once they get wider testing.

The memset() in fixup_convert_atmel_pri is supposed to zero out

out something way outside the struct instead. Fix this potentially

In some special case (padding because of sync
or umount) it can be possible that summary
information is not fit to the end of the erase
block. In these cases the collecting of summary

The problem was that this was not respected
by jffs2_sum_add_kvec(). This patch fix this

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.

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)

Fix of performance and stability issues on Intel NOR chips. It fixes:
1. Very low write performance on Sibley (perf tests demonstrated write
performance less than 100Kb/sec when it should be over 400Kb/sec).
2. Low erase performance. (perf tests on Sibleuy demonstrated erase
performance 246Kb/sec when it should be over 300Kb/sec).
3. Error on JFFS2 tests with CPU loading application when MTD returns
"block erase error: (status timeout)" To fix the issue it does the
following:
1. Removes the timeout tuning from inval_cache_and_wait_for_operation.
2. Waiting conditions in inval_cache_and_wait_for_operation now is
based on timer resolution
If timeout is lower than timer resolution then we do in cycle
"Checking the status"
udelay(1);
cond_resched();
If timeout is greater than timer resolution (probably erase
operation) We do the following
sleep for half of operation timeout and do in cycle the following
"Checking the status"
sleep for timer resolution

Trying to pass kernel command line arguments to block2mtd at boot-time does
not work currently. block2mtd_setup() is called so early that kmalloc()
fails nevermind being able to do open_bdev_excl() (which requires rootfs to
be mounted. This patch only saves the option string at the early boot stage,
and parses them later when block2mtd_init() is called. If open_bdev_excl()
fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it
possible to initialize the driver before rootfs has been mounted. Also gets
rid of the superfluous parse_name() that only checks if name is longer than
80 chars and copies it to a string that is not kfreed.
With this patch, I can boot statically compiled block2mtd, and mount jffs2
as rootfs (without modules or initrd), with lilo config like this:
root=/dev/mtdblock0
append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536"
(Note that rootfstype=jffs2 is required, since the kernel only tries
filesystems without "nodev" attribute by default, and jffs is "nodev").
Compared to first version of this patch, this one does not copy the
parameters to the global buffer if init has already been called, and the
global array is marked as __initdata.
Compared to the second version of this patch, module build is fixed.
Compared to the third version of this patch, statically compiled block2mtd
driver with no boot-time parameter no longer gives spurious error 'cannot
open device ""'
