| * | mtd: nand: extend NAND flash detection to new MLC chipsMarcus Folkesson2012-09-162-19/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the newer MLC devices have a 6-byte ID sequence in which several field definitions differ from older chips in a manner that is not backward compatible. This method is already used in the Linux Kernel. Signed-off-by: Marcus Folkesson <marcus.folkesson@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | mtd nand: implement buswidth detectionSascha Hauer2012-08-031-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new NAND_BUSWIDTH_AUTO flag which can be used to automatically detect the nand buswidth. The id is always read in 8bit mode. An additional callback is needed to switch the nand controller into 16bit mode. This currently depends on a safe read_byte (always) and read_buf (for onfi-only flashes) callback. It has been tested on OMAP, but is not something that generally works. For this reason the existence of the set_buswidth callback is used to determine whether we are able to do autodetection or not. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | - dev_ready is supposed to return whether the device is ready or not, not to poll until the device is ready. - dev_ready should return true for ready and false for not ready - waitpin polarity is not needed (at least the kernel does not have it) - wait_mon_mask must be 32bit. The code was unused since no board specified a wait pin, so no breakage included. This also removes the now unused timeout variable from platformdata.
