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.
