[U-Boot] [PATCH] NAND: Add Micron MT29F16G identifier

[U-Boot] [PATCH] NAND: Add Micron MT29F16G identifier

[Chunhe Lan]

The Micron MT29F16G parts are 2048Mbytes x 8 bits 3.3V
parts with the 0x48 identifier. Add these to the list
of known devices IDs.

I added same ids, the device was able to be detected, but the nand info, nand
erase.chip did not work.  Same command works for a Micron 512MBytes nand. I
am using mxc_nand driver. What else do we need update? what change you made
to the mxc_nand.c and board configuration .h file?

isn't your flash an ONFI one ?

This ID is wrong as if will return the same for (at least) MT29F16G and
MT29F32G : you need to use ONFI to detect this kind of flashes.
