[PATCH 00/12] Partition table manipulation support

[Sascha Hauer <s.hauer@pengutronix.de>]

This series adds support for changing partition tables. There is both a
C API and a new command to create partition tables, to create partitions
or to delete partitions. Both MSDOS and GPT tables are supported,
although MSDOS currently lacks support for logical partitions which is
left as a future exercise.

The partition manipulation command mimics GNU Parted which has a quite
convenient API for use in scripts. Some examples for the command are:

Print a partition table:

$ parted mmc0 print

create a new partition table:

$ parted mmc0 mklabel gpt

create a new partition table and add a partition beginning at offset
1MiB ending at offset 128MiB:

$ parted mmc0 mklabel gpt mkpart rootfs ext4 1MiB 128MiB

The same, using KiB as unit and printing the result at the end:

$ parted mmc0 unit KiB mklabel gpt mkpart rootfs ext4 1024 131072 print

Original GNU Parted has several heuristics to adjust a new partition's
borders between existing partitions. These have all been left out so
far. Also toggling a bootable flag is not yet implemented. So there are
still things to do, but I think this is enough to be useful already.
