priority yesterday, but i still can't estimate the time. There is no 
document or change list showing the difference between m8/b and gxl/axg 
serial chips. Now it seems that we can't use command NFC_CMD_N2M on nand 
initialization for m8/b chips and use *read byte from NFC fifo register* 
instead.
