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.

Convert cmd_usage() calls in common to use a return value

2012-03-06T20:09:46+00:00

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

UBI: Fix error code handling in ubi commands

2011-03-21T09:02:16+00:00

Some ubi commands returned negative error codes, resulting in
the following error message on the prompt:

"exit not allowed from main input shell."

Negative error codes are not allowed.

This patch now changes the UBI code to return positive error codes.
Additionally "better" error codes are used, for example "ENOMEM" when
no memory is available for the UBI volume creation any more.

Also the output of some commands is enhanced:

Before:

=> ubi read 100000 testvol 100000
Volume testvol found at volume id 0
read 1048576 bytes from volume 0 to 100000(buf address)
=> ubi write 100000 testvol 1000
Volume testvol found at volume id 0

After:

=> ubi read 100000 testvol 100000
Read 1048576 bytes from volume testvol to 00100000
=> ubi write 100000 testvol 1000
4096 bytes written to volume testvol

UBI/UBIFS: Automatically unmount UBIFS volume upon UBI partition change

Automatically unmount UBIFS partition when user changes the UBI device.
Otherwise the following UBIFS commands will crash.

various cmd_* files: fixed layout a little bit

2010-08-08T23:07:37+00:00

Most of the files have U_BOOT_CMD on a separate line,
but a few didn't and had the first line on the same line
as U_BOOT_CMD.

This changes these files by adding a line break and a tab

cmd_usage(): simplify return code handling

2010-07-24T18:43:57+00:00

Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.
