[PATCH 00/13] ubifs update

[Alexander Stein]

Hi,

this patch set updates ubifs to the u-boot v2016.03 one. This most importantly
uses write buffer size (defined by flash itself) for recovering. This is done
(and required!) by Linux since commit 2765df7da ("UBIFS: use max_write_size
 during recovery") which is included in v2.6.39-rc1. Failing to do so results
in false error detection and mount failure.

Some comments on the patches itself. Most of them are to add defines or
functions required by new ubifs code. They all include more detailed
information.

Patch 1,2:
* Required to pass write buffer size to ubifs

Patch 9 ("ARM: Add atomic.h from u-boot v2016.03"):
* The most troublesome as it only adds support for arm. I've yet to find out
  if atomic_t is _really_ required in ubifs, but I'm not so far into that code
  to decide it. Maybe there are better possibilities to support all
  architectures.

The patches are based on current origin/master a0fa6e1d2b6ac5
("Merge branch 'for-next/squashfs'") including a single patch for our custom
hardware. They are compiled tested using git test-sequence. The final barebox
successfully mounts the damaged ubifs while the previous one doesn't.
I'm keen to get feedback.

Best regards,
Alexander
