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.

Fast insert and remove sd card make edma equeue, dequeue
frequently. And with unstable fifo data err, if we stop edma, it
terminate all data will been sent later and flush that desc. However,
MHSC hardware fifo byte counter in fault state because avaliable data
isn't enough, and remain data been teminated by stop edma. So edma req
signal in fault state event we restart edma. We just let edma sent remain
data, and reset fifo to drop these unused data.
