Add multi chip support to the FSL-UPM driver
This patch adds support for multi-chip NAND devices to the FSL-UPM driver. The "dev_ready" callback of the "struct fsl_upm_nand" is now called with the argument "chip_nr" to allow testing the proper chip select line. The NAND support of the MPC8360ERDK is updated as well. No other boards are currently using the FSL UPM driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
