sunxi_flash - sunxi_flash sub-system

Usage:
sunxi_flash read command parmeters :
parmeters 0 : addr to load(hex only)
parmeters 1 : the name of the part to be load
[parmeters 2] : the number of bytes to be load(hex only)
if [parmeters 2] not exist, the number of bytes to be load is the size of the part indecated on partemeter 1
boota: bad boot image magic, maybe not a boot.img?
