| * mtd core: call driver write function with complete bufferSascha Hauer2012-12-071-53/+3
| | | | | | | | | | | | | | | | | | | | mtd->write is supposed to loop around pages internally, no need to do this in mtd_write. This fixes a huge write performance drop with the m25p80 driver when it was converted to a mtd driver recently. Since mtd->writesize is 1 for this driver mtd_write ended up doing single byte writes on the flash. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * mtd nand: allow partial page writesSascha Hauer2012-12-071-7/+0
| | | | | | | | | | | | | | | | | | | | | | The nand layer handles partial page writes just fine. If the start or end of the data is not page aligned, the nand layer will copy the data to a temporary page buffer. Remove the check which disallows partial page writes since this is what we want to do on barebox when for example an image is written to nand which is not padded to page size.

* | mtd: nand: mxs: reset BCH earlier, too, to avoid NAND startup problemsWolfram Sang2012-12-061-3/+10
|/ | | | | | | | | | | It could happen (1 out of 100 times) that NAND did not start up correctly after warm rebooting, so barebox could not find its environment or DMA timed out due to a stalled BCH. When resetting BCH together with GPMI, the issue could not be observed anymore. We probably need the consistent state already before sending commands to NAND.

| | | | | | | | | | | As in the kernel we revert as this was supposed to work but does not yet this may need more work on the smc to be able to use it So for now revert it This reverts commit 809f0f6327241504b5071622a8d573255f91a875.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
