2013-09-11block: support embedded device command line partitionCai Zhiyong
Read block device partition table from command line. The partition used for fixed block device (eMMC) embedded device. It is no MBR, save storage space. Bootloader can be easily accessed by absolute address of data on the block device. Users can easily change the partition.

2013-07-09partitions: add aix lvm partition support filesPhilippe De Muyter
Add partitions/aix.h and partitions/aix.c. AIX LVM permits to make "logical volumes" which are made of multiple slices of multiple disks. The new code allows only access to the "logical volumes" which are made of one slice on the probed disk, a slice being a contiguous disk area. The code also detects "logical volumes" made of multiple slices on the probed disk, but can not describe them to the partition layer, because the partition layer generic code does not support that. When such non-contiguous "logical volumes" are detected, a diagnostic message is printed.
