I have finished the code for mx50's GPMI.
And I am coding for the MX6's GPMI recently.

I need a separate mx50-hal (or mx60-hal) to make the code tidy.
The MX50 and mx60 support ONFI NAND and TOGGLE nand(which mx23/mx28 do 
not support),
they need a long code to initialize the TIMING register. What's more, 
the READ/WRITE functions
are different from the mx23/mx28.

Frankly speaking, I can merge the mxs-hal.c file to the gpmi-nfc.c, but 
don't you think it too
messy?
