| * [JFFS2] Use MTD_OOB_AUTO to automatically place cleanmarker on NANDArtem Bityutskiy2007-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nowadays MTD supports an MTD_OOB_AUTO option which allows users to access free bytes in NAND's OOB as a contiguous buffer, although it may be highly discontinuous. This patch teaches JFFS2 to use this nice feature instead of the old MTD_OOB_PLACE option. This for example caused problems with OneNAND. Now JFFS2 does not care how are the free bytes situated. This may change position of the clean marker on some flashes, but this is not a problem. JFFS2 will just re-erase the empty eraseblocks and write the new (correct) clean marker.

| | | | | | | | | | | | | | | | | | | | | | | | Remove unused and broken mtd->ecctype and mtd->eccsize fields from struct mtd_info. Do not remove them from userspace API data structures (don't want to breake userspace) but mark them as obsolete by a comment. Any userspace program which uses them should be half-broken anyway, so this is more about saving data structure size.

There is only one user of them and they are used locally just for printing. Anyway, this patch is a preparation for removing mtd->ecctype and mtd->eccsize, but these macros use them. Fix this.

| | | | | | | | | | | | | | | | | | The cfi_staa_write_buffers() uses mtd->eccsize but means mtd->writesize. BTW, mtd-eccsize is broken and is not initialized, which means the code fixed by this patch is broken/unused anyway.

| * [MTD] OneNAND: Invalidate bufferRAM after eraseAdrian Hunter2007-02-09
| | | | | | | | | | | | | | | | | | | | OneNAND has internal bufferRAMs. The driver keeps track of what is in the bufferRAM to save having to load from the NAND core. After an erase operation, the driver must mark bufferRAM invalid if it refers to the erased block.

| * [MTD] [NAND] Correctly validate out-of-band offset and lengthAdrian Hunter2007-02-09
| | | | | | | | | | | | | | | | | | | | | | | | Add checks to ensure that out-of-band reads and writes are not attempted with an invalid offset or length. Specifically, the offset must be less than the size of oob for a page and the length must not go beyond the size of the device. Additionally the checks must adjust for auto-placement (MTD_OOB_AUTO) of oob data. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| * [MTD] Fix default timeouts for Intel NOR flashDavid Woodhouse2007-02-09
| | | | | | | | | | | | | | | | | | | | In commit c172471b78255a5cf6d05383d9ebbf0c6683167a Nico switched to using common code for polling for command completion. Unfortunately he also used a common default timeout for both write and erase commands, despite the fact that erases can take a _whole_ lot longer. Use a more sensible default for erase timeout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OneNAND double-density package (DDP) has two chips, each with their own bufferRAM. The driver will skip loading data from the NAND core if the data can be found in a bufferRAM, however in that case, the correct chip's bufferRAM must be selected before reading from bufferRAM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When write-verify is enabled (CONFIG_MTD_ONENAND_VERIFY_WRITE), the data written is read back and compared. The comparison was being made between dataRAM buffers, but this does not verify that the data made it to the dataRAM correctly in the first place.
