nand_ecclayout is present in mtd.h at Linux.
Move this structure to mtd.h to comply with Linux.Also, increase the ecc placement locations to 640 to suport device having
writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone
up to 640 bytes and consequently the maximum ecc placement locations have
also gone up to 640.Changes from Prabhabkar's version (squashed into one patch to preserve
bisectability):
- Added _LARGE to MTD_MAX_*_ENTRIESThis makes the names match current Linux source, and resolves
a conflict between
http://patchwork.ozlabs.org/patch/280488/
and
http://patchwork.ozlabs.org/patch/284513/The former was posted first and is closer to matching Linux, but
unlike Linux it does not add _LARGE to the names. The second adds
_LARGE to one of the names, and depends on it in a subsequent patch
(http://patchwork.ozlabs.org/patch/284512/).- Made max oobfree/eccpos configurable, and used this on tricorder,
alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build
for me without doing so, due to a size increase).On tricorder SPL, this saves 2576 bytes (and makes the SPL build
again) versus the new default of 640 eccpos and 32 oobfree, and
saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.Signed-off-by: Prabhakar Kushwaha

Linux modified the MTD driver interface in commit edbc4540 (with the
same name as this commit). The effect is that calls to mtd_read will
not return -EUCLEAN if the number of ECC-corrected bit errors is below
a certain threshold, which defaults to the strength of the ECC. This
allows -EUCLEAN to stop indicating "some bits were corrected" and begin
indicating "a large number of bits were corrected, the data held in
this region of flash may be lost soon". UBI makes use of this and when
-EUCLEAN is returned from mtd_read it will move data to another block
of flash. Without adopting this interface change UBI on U-boot attempts
to move data between blocks every time a single bit is corrected using
the ECC, which is a very common occurance on some devices.For some devices where bit errors are common enough, UBI can get stuck
constantly moving data around because each block it attempts to use has
a single bit error. This condition is hit when wear_leveling_worker
attempts to move data from one PEB to another in response to an
-EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is
called to perform the data copy, and after the data is written it is
read back to check its validity. If that read returns UBI_IO_BITFLIPS
(in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to
wear_leveling worker, which then proceeds to schedule the destination
PEB for erasure. This leads to erase_worker running on the PEB, and
following a successful erase wear_leveling_worker is called which
begins this whole cycle all over again. The end result is that (without
UBI debug output enabled) the boot appears to simply hang whilst in
reality U-boot busily works away at destroying a block of the NAND
flash. Debug output from this situation:UBI DBG: ensure_wear_leveling: schedule scrubbing

...This patch adopts the interface change as in Linux commit edbc4540 in
order to avoid such situations. Given that none of the drivers under
drivers/mtd return -EUCLEAN, this should only affect those using
software ECC. I have tested that it works on a board which is
currently out of tree, but which I hope to be able to begin
upstreaming soon.Signed-off-by: Paul Burton

This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).To produce this update I used tag v3.7.1 of linux-stable repository.
The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.Signed-off-by: Sergey Lapin

This patch adds a driver for the diskonchip G4 nand flash device. It is based
on the driver from the linux kernel.This also includes a separate SPL driver. A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly). The SPL driver basically mimics how
a typical IPL reads data from the device. The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints). Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.[port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d]

Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.This driver supports both host and peripheral modes.
This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.Virtual root hub device is not implemented.
Known problems: with no devices connected usb_lowlevel_start() fails.
