467622ef2a [MTD] [NOR] Fix cfi_send_gen_cmd handling of x16 devices in x8 mode (v4)
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.

d4430d62fa [PATCH] beginning of methods conversion
To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
	1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both.  That's this changeset.
	2) for each driver convert to new methods.  *ALL* drivers
are converted in this series.
	3) kill the old (renamed) methods.

Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain.  The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.

New methods:
	open(bdev, mode)
	release(disk, mode)
	ioctl(bdev, mode, cmd, arg)		/* Called without BKL */
	compat_ioctl(bdev, mode, cmd, arg)
	locked_ioctl(bdev, mode, cmd, arg)	/* Called with BKL, legacy */

8a1a627205 Revert "[MTD] m25p80.c code cleanup"
This reverts commit 75d0ee2202.

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.

be8f78b8e8 [MTD] [NOR] AT49BV6416 has swapped erase regions
The CFI information read from AT49BV6416 lists the erase regions in the
wrong order, causing problems when trying to erase or update the first
or last 64KiB block.

Work around this by inverting the "top boot" flag, which will
effectively reverse the order of the erase regions.

This chip is obsolete, but it's used in some existing designs.

87e92c062b [MTD] cfi_cmdset_0002.c: Add Macronix CFI V1.0 TopBottom detection
This patch adds TopBottom detection for most Macronix chips with CFI V1.0.

The main purpose of this patch is to add detection of the MX29LV400C B
used on the LaCie Ethernet Disk mini V2 NAS.

It detects the following parts correctly:-
MX28F640C3B T
MX29LV002C  B
MX29LV002NC B
MX29LV004C  T
MX29LV400C  T/B
MX29LV800C  T/B
MX29LV160C  T/B
MX29SL800C  T/B
MX29SL802C  T/B

It detects the following uniform part as bottom but it should work
correctly:-
MX29LV040C

For T parts it causes the erase block table to be reversed correctly.
For other parts it avoids the bogus "Assuming top" message.

It does not detect the following correctly:-
MX28F640C3B B
MX29LV002C  T
MX29LV002NC T
MX29LV004C  B
MX29SL400C  T/B
MX29SL402C  T/B

If desired I could supply a more complicated patch to handle these as
well.

Only the MX29LV400C B has been physically tested; others were checked
against their data sheets.

93a22f8b95 omap drivers: switch to standard GPIO calls
This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.

This is all fairly brainless/obvious stuff.  Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads.  (That would improve
with hardware IRQ debouncing enabled, of course...)

3fc2389847 [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly written
The functions that write the OOB info (on hardware ECC only) use the 
HW_SYNDROME method.

This is not correct : the start position is "pos = eccsize + chunk" and 
should be eccsize. So, the standard (nand_write_oob_std) function should 
be used. This patch corrects this by using NAND_ECC_HW instead of 
NAND_ECC_HW_SYNDROME.

This has only been tested on small pages nand flash.
(if anyone can test it on large pages that would be great).

13f5369704 [MTD] [NAND] driver extension to support NAND on TQM85xx modules
This patch extends the FSL UPM NAND driver from Anton Vorontsov to
support hardware which does not have the R/B pin of the NAND chip
connected, like the TQM8548 module:

- The OF_GPIO dependency has been removed from the Kconfig option
  because GPIO is not needed. The relevant gpio_* function are then
  stubbed out in <linux/gpio.h>.

- It re-introduces the chip-delay property to define an appropriate
  maximum delay time (tR) required for read operations. The binding
  will be documented in a separate patch.

  chip-specific, and we should always do waits. I saw one board that
  didn't need fsl,wait-pattern, but I assume this was the exception
  that proves the rule;
- Get rid of chip-delay. Today there are no users for this, and if
  anyone really need this they should push the OF bindings beforehand;
- Now flash chips should be child nodes of the FSL UPM NAND controller;
- Implement OF partition parsing.

fdc53971bc Support 'discard sectors' operation.
We can benefit from knowing that the file system no longer cares about
the contents of certain sectors, by throwing them away immediately and
then never having to garbage collect them, and using the extra free
space to make our operations more efficient. Do so.

63fd7f30f3 [MTD] [INFTL] Fix infinite loop in INFTL_foldchain
When iterating over a chain in reverse (oldest block first), this
patch correctly marks the PUtable[] entry of the second to last erase
block of a chain as BLOCK_NIL, regardless of whether or not it can
format the last block successfully. Before, the second to last block
was only marked as pointing to BLOCK_NIL if INFTL_formatblock()
succeeded on the last block of the chain, which could potentially
result in an infinite loop if the block was worn out and refused to
format.
