Cai Zhiyong bab55417b1 block: support embedded device command line partition
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.

This code reference MTD partition, source "drivers/mtd/cmdlinepart.c"

Philippe De Muyter 6ceea22bbb partitions: add aix lvm partition support files
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.
