[U-Boot] 8/16 bit support for NAND at runtime

2010-03-04 Thread Vipin KUMAR
Hi All, This query is wrt NAND 8/16 bit device support at runtime. Currently, the u-boot code can support only one of these at a time. Although the NAND device in itself can be recognized by reading the device id, the NAND controllers may need different platform specific initializations for diffe
