MTD: Change cfi-mtd to accept non-uniform sector sizes

2009-04-29T09:06:06+00:00

With this patch non-uniform NOR FLASH chips (chips with multiple erase
regions) can be exported via the cfi-mtd layer and therefor used by UBI.
We select the largest sector size as erasesize. The cfi driver will make
sure that the smaller sectors are handled correctly.

mtd: nand/onenand: Register mtd device upon device scanning

2009-04-27T23:15:38+00:00

With this patch the NAND and OneNAND devices are registered in the MTD
subsystem and can then be referenced by the mtdcore code (e.g.
get_mtd_device_nm()). This is needed for the new "ubi part" command
syntax without the flash type parameter (nor|nand|onenand).

mtd: nand: Include linux/mtd/partitions.h in nand_base.h

2009-04-27T23:15:37+00:00

This patch removes this compilation warning when CONFIG_MTD_PARTITIONS is
defined:

nand_base.c: In function 'nand_release':
nand_base.c:2922: warning: implicit declaration of function 'del_mtd_partitions'

CMD_UBI != MTD_PARTITIONS

2009-04-16T21:03:27+00:00

Fix dependency goofage:  it should certainly be possible to have the
partition support without bringing in UBI commands.

Blackfin: nand: flush peripheral before polling it

2009-04-06T21:37:37+00:00

We need to make sure the data written to the nand flash controller makes
it there before we start polling its status register.  Otherwise, we may
get stale data and return before the controller is actually ready.

UBI/cfi-mtd: Fix mtd name for multiple chips

2009-04-04T21:25:40+00:00

On platforms with multiple NOR chips, currently only the first one
can be selected using the "ubi part" command. This patch fixes this
problem by using different names for the NOR "mtd devices".

It also changes the name of the NOR MTD device from "cfi-mtd" to
"norX" (X indexing the device numer) to better match the mtdparts
defaults.

Add support for the AT91RM9200EK Board.

2009-04-04T18:42:20+00:00

The AT91RM9200-EK Evaluation Board supports the AT91RM9200
ARM9-based 32-bit RISC microcontroller and enables real-time code development
and evaluation.

Here is the chip page on Atmel website:

Merge branch 'master' of git://git.denx.de/u-boot-nand-flash

Noisily disable the legacy NAND subsystem.

2009-04-03T20:27:26+00:00

Legacy NAND is marked for feature removal after April 2009 (i.e. this
upcoming release).  There are still several boards that reference it
(though many do so only for disk-on-chip support which has been silently
disabled for a while now).  These boards will now fail to build
with #error, though the code is still there if the user removes #error.

The plan is to remove the code outright in the next release, along with
any board code that refers to it (such as board/esd/common/auto_update.c).

Also, remove the legacy NAND API description from README.nand.

sf: stmicro: dont send 4 bytes when reading status register

2009-04-02T16:51:28+00:00

I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result.  Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately.  So only write out the
read status register opcode before polling the result.
