    mtd: mxc-nand: Implement support for PARAM command · 3d6e81c0
    Uwe Kleine-König authored
    The mxc-nand driver never supported the PARAM command to read out the
    ONFI parameter page and so always relied on probing my manufacturer and
    device id (as provided by the READID command).
    
    This patch implements reading out the first parameter page copy at least
    which should be good enough in practise.
    
    This makes the boot log change from
    
    	nand: device found, Manufacturer ID: 0x2c, Chip ID: 0xb1
    	nand: Micron NAND 128MiB 1,8V 16-bit
    
    to
    	nand: device found, Manufacturer ID: 0x2c, Chip ID: 0xb1
    	nand: Micron MT29F1G16ABBDAH4
    
    on my machine.
