dfu, nand: before write a buffer to nand, erase the nand sectors

2013-06-24T23:17:23+00:00

before writing the received buffer to nand, erase the nand
sectors. If not doing this, nand write fails. See for
more info here:

http://lists.denx.de/pipermail/u-boot/2013-June/156361.html

Using the nand erase option "spread", maybe overwrite
blocks on, for example another mtd partition, if the
erasing range contains bad blocks.
So a limit option is added to nand_erase_opts()

mtd: resync with Linux-3.7.1

2013-05-31T22:12:03+00:00

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.

nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters

2013-04-10T13:22:22+00:00

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for.  We also make them take an
loff_t limit on how much data can be read or written.  This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks.  To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well.  All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

The changes were started by Pantelis and finished by Tom.

nand: Add torture feature

2012-11-26T21:41:29+00:00

This patch adds a NAND Flash torture feature, which is useful as a block stress
test to determine if a block is still good and reliable (or should be marked as
bad), e.g. after a write error.

This code is ported from mtd-utils' lib/libmtd.c.

nand: Make NAND lock status compatible with Micron

2012-09-17T22:33:43+00:00

Micron NAND flash (e.g. MT29F4G08ABADAH4) BLOCK LOCK READ STATUS is not
the same as others.  Instead of bit 1 being lock, it is #lock_tight.
To make the driver support either format, ignore bit 1 and use only
bit 0 and bit 2.
