Move malloc_cache_aligned() to its own header

2015-09-11T21:15:16+00:00

At present malloc.h is included everywhere since it recently was added to
common.h in this commit:

   4519668 mtd/nand/ubi: assortment of alignment fixes

This seems wasteful and unnecessary. We have been trying to trim down
common.h and put separate functions into separate header files and that
change goes in the opposite direction.

Move malloc_cache_aligned() to a new header so that this can be avoided.
The header would perhaps be better named as alignmem.h but it needs to be
included after common.h and people might be confused by this. With the name
memalign.h it fits nicely after malloc() in most cases.

mtd/nand/ubi: assortment of alignment fixes

2015-08-28T16:33:17+00:00

Various U-Boot adoptions/extensions to MTD/NAND/UBI did not take buffer
alignment into account which led to failures of the following form:

ERROR: v7_dcache_inval_range - start address is not aligned - 0x1f7f0108
ERROR: v7_dcache_inval_range - stop address is not aligned - 0x1f7f1108

common, ubi: use positive return values for ubi check

2015-04-10T15:54:06+00:00

The ubi check command is expected to not fail and just check whether
a volume exist or not. Currently, when a volume does not exist, the
command fails which leads to an error:
"exit not allowed from main input shell."

Use 1 to indicate that a volume does not exist. This allows to use
ubi check in an if statement, e.g.
if ubi check rootfs; then; echo "exists"; else; echo "not there"; fi

mtd, ubi, ubifs: resync with Linux-3.14

2014-08-25T23:25:55+00:00

resync ubi subsystem with linux:

commit 455c6fdbd219161bd09b1165f11699d6d73de11c
Author: Linus Torvalds 
Date:   Sun Mar 30 20:40:15 2014 -0700

    Linux 3.14

A nice side effect of this, is we introduce UBI Fastmap support
to U-Boot.

common: commands: make commands static

2014-07-18T21:53:23+00:00

Since most commands are not public, make them static. This
prevents warnings that no common prototype is available.

cmd_ubi: add write.part command, to write a volume in multiple parts

2013-10-09T17:52:22+00:00

This allows you to write data to an UBI volume when the amount of memory
available to write that data from is less than the total size of the
data. For example, you may split a root filesystem UBIFS image into
parts, provide the total size of the image to the first write.part
command and then use multiple write.part commands to write the
subsequent parts of the volume. This results in a sequence of commands
akin to:

  ext4load mmc 0:1 0x80000000 rootfs.ubifs.0
  ubi write.part 0x80000000 root 0x08000000 0x18000000
  ext4load mmc 0:1 0x80000000 rootfs.ubifs.1
  ubi write.part 0x80000000 root 0x08000000
  ext4load mmc 0:1 0x80000000 rootfs.ubifs.2
  ubi write.part 0x80000000 root 0x08000000

This would write 384MiB of data to the UBI volume 'root' whilst only
requiring 128MiB of said data to be held in memory at a time.

cmd_ubi: use int64_t volume size for 'ubi create'

2013-10-09T17:52:20+00:00

int64_t matches the bytes field in struct ubi_mkvol_req to which the
size is assigned. With the prior signed 32 bit integer, volumes were
restricted to being less than 2GiB in size.
