mtd: move & update nand_ecclayout structure (plus board changes)

2013-11-21T19:32:43+00:00

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_*_ENTRIES

   This 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.

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.

Convert ISO-8859 files to UTF-8

2011-08-04T21:34:02+00:00

There was a mix of UTF-8 and ISO-8859 files in the U-Boot source
tree, which could cause issues with the patchwork review system.
This commit converts all ISO-8859 files to UTF-8.

mtd: add an mtd method for get_len_incl_bad()

2010-10-11T20:11:00+00:00

The logic to 'spread' mtd partitions needs to calculate the length in
the mtd device, including bad blocks.

This patch introduces a new function, mtd_get_len_incl_bad that can
return both the length including bad blocks and whether that length
was truncated on the device. This new function will be used by the
mtdparts spread command later in this series. The definition of the
function is #ifdef'd out in configurations that do not use the new
'mtdparts spread' command.

nand: remove dead code and suspend/resume

2010-10-11T20:10:35+00:00

Get rid of the several "#if 0" sections that were keeping around Linux
code that isn't relevant to U-Boot.  Besides cluttering the code, these
sections make tracking upstream changes harder, rather than easier.
It's easy to discard obviously irrelevant diff hunks that patch rejects,
but it's not as easy to notice hunks that apply cleanly to the #if 0
section, but *are* relevant to U-Boot and require modification elsewhere.

Also remove suspend/resume, as this is not applicable to U-Boot.  Removal
saves 232 bytes on powerpc.

mtd: Update MTD infrastructure to support 64bit device size

2009-06-12T18:45:47+00:00

This patch brings the U-Boot MTD infrastructure in sync with the current
Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size
support and a resync of the mtdpart.c file which has seen multiple fixes
meanwhile.

NAND: sync with 2.6.27

2008-10-29T15:42:16+00:00

This brings the core NAND code up to date with the Linux kernel.

Since there were several drivers in Linux as of the last update that are
not in u-boot, I'm not bringing over new drivers that have been added
since in the absence of an interested party.

I did not update OneNAND since it was recently synced by Kyungmin Park,
and I'm not sure exactly what the common ancestor is.
