Alexey Korolev 60f26520e7 [MTD] LPDDR Makefile and KConfig
We have two components to manage LPDDR flash memories in Linux.
1. It is a driver for chip probing and reading its capabilities
2. It is a device operations driver.

Alexey Korolev d81408304b [MTD] LPDDR extended physmap driver to support LPDDR flash
Physmap is a generic map driver for different platforms and flash types.
We added support of LPDDR to physmap.
All changes here are related to introduction of new pfow_base parameter.
This parameter is valid in case of LPDDR chips only.

Matt Reimer 5b0d4d7c8a [MTD] [NAND] pxa3xx: convert from ns to clock ticks more accurately
The various fields in NDTR{01} are in units of clock ticks minus one, but the
ns2cycle macro mistakenly adds one, inflating the number of clock ticks and
making it impossible to set any of these fields to zero.

Matt Reimer 7f9938d0fd [MTD] [NAND] pxa3xx: fix non-page-aligned reads
Reads from non-page-aligned addresses were broken because while the
address to read from was correctly written to NDCB*, a full page was
always read. Fix this by ignoring the column and only using the page
address.

I suspect this whole-page behavior is due to the controller's need to
read the entire page in order to generate correct ECC. In the non-ECC
case this could be optimized to use the column address, and to set the
read length to what is being requested rather than the length of an
entire page.

Julia Lawall 232ed5e68a [MTD] [NAND] alauda: use USB API functions rather than constants
This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

Artem Bityutskiy d85316ac45 [MTD] fix m25p80 64-bit divisions

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!

'do_div'. This patch also change some print placeholders to

Adrian Hunter 69423d99fc [MTD] update internal API to support 64-bit device size
MTD internal API presently uses 32-bit values to represent
device size.  This patch updates them to 64-bits but leaves
the external API unchanged.  Extending the external API
is a separate issue for several reasons.  First, no one
needs it at the moment.  Secondly, whether the implementation
is done with IOCTLs, sysfs or both is still debated.  Thirdly
external API changes require the internal API to be accepted
first.

Note that although the MTD API will be able to support 64-bit
device sizes, existing drivers do not and are not required
to do so, although NAND base has been updated.

In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
    	- printk message formats
    	- division and modulus of 64-bit values
    	- NAND base support
	- 32-bit local variables used by mtdpart and mtdconcat
	- naughtily assuming one structure maps to another
	in MEMERASE ioctl

Alexey Korolev 8a4c2495b1 MTD: nandsim: use less RAM
Nandsim consumes ~2x more RAM than the density of simulated device.
It becomes critical if we need to simulate 256MB NAND and run stress tests
on it.

We investigated the reasons. nandsim allocates space for pages using kmalloc
function. The size of LP nand page is 2112 bytes.
kmalloc gets space from slab pools by chunks 2^n. So if we need to kmalloc
2112 bytes, 4096 bytes will be consumed by system.
The best way to avoid this issue would be using kmem_cache allocations. AFAIK
this mechanism specially designed to handle cases when arrays of allocations
are used.

Artem Bityutskiy ed45819f31 UBI: fix warnings when debugging is enabled
The 'ubi_io_read_vid_hdr()' and 'ubi_io_read_ec_hdr()' function
have the 'verbose' argument which controls whether they should
print a warning if the VID/EC header was not found or was corrupted.
Some callers require the headers to be OK, and pass 1. Some allow
a corrupted/not present header, and pass 0.

       if (UBI_IO_DEBUG)
               verbose = 1;

And UBI_IO_DEBUG is 1 if CONFIG_MTD_UBI_DEBUG_MSG_BLD is true. So in
this case the warning is printed all the time. This confuses people.

Thus, do not print the messages as warnings if UBI_IO_DEBUG is true,
but print them as debugging messages instead.

Eric W. Biederman 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.
