In order to avoid code duplication, let's consolidate the ECC setting for all SoC variants. Such decision is based on page size and ECC strength requirements. Also, provide a default value for the case where such ECC information is not provided (non-ONFI devices). Tested-by:

Currently, we have two different cmdfunc's implementations: one for PXA3xx SoC variant and one for Armada 370/XP SoC variant. The former is the legacy one, typically constrained to devices with page sizes smaller or equal to the controller's FIFO buffer. On the other side, the latter _only_ supports the so-called extended command semantics, which allow to handle devices with larger page sizes (4 KiB, 8 KiB, ...). This means we currently don't support devices with smaller pages on the A370/XP SoC. Fix it by first renaming the cmdfuncs variants, and then make the choice based on device page size (and SoC variant), rather than SoC variant alone. While at it, add a check for page size, to make sure we don't allow larger pages sizes on the PXA3xx variant. Tested-by:

Currently the driver assumes all commands will eventually trigger a RnB transition, and thus a "device is ready" IRQ. This assumption means that on every issued command, the dev_ready completion handler is init'ed and the need_wait flag is set. However this is incorrect: some commands (such as NAND_CMD_STATUS) don't make the device 'busy' and thus a RnB transition never occurs. Given, the NAND core never calls waitfunc() after such commands, this is not a problem. Therefore, it's possible to only clear the need_wait flag on every command that is started. This fixes a current bug that can be reproduced on PXA boards by writing blank (all 0xff'ed) to a page: 1. The kernel issues NAND_CMD_STATUS and sets need_wait=1. The flag won't be cleared for this command since no RnB transition is involved. 2. NAND_CMD_PAGEPROG is issued but since the data is blank, the driver decides not to execute the command (and no IRQ activity is involved). 3. The NAND core calls waitfunc() and waits for the dev_ready completion, which will never end since the device _is_ already ready. Tested-by: -

This patch marks the function is_erased() as static in denali.c because it is not used outside this file. This patch elimiates the following warning in nand/denali.c: drivers/mtd/nand/denali.c:900:6: warning: no previous prototype for ‘is_erased’ [-Wmissing-prototypes] Signed-off-by:

This patch marks the functions do_write_buffer() and do_erase_oneblock() as static because because they are not used outside this file. It also removes the unused function word_program() in lpddr/lpddr_cmds.c. Thus, it also removes the following warnings in lpddr/lpddr_cmds.c: drivers/mtd/lpddr/lpddr_cmds.c:391:5: warning: no previous prototype for ‘do_write_buffer’ [-Wmissing-prototypes] drivers/mtd/lpddr/lpddr_cmds.c:472:5: warning: no previous prototype for ‘do_erase_oneblock’ [-Wmissing-prototypes] drivers/mtd/lpddr/lpddr_cmds.c:751:5: warning: no previous prototype for ‘word_program’ [-Wmissing-prototypes] Signed-off-by:

This driver doesn't need its own custom chip->write_page callback; the only "custom" requirement is that this driver does not support subpage writes, which we can avoid using the NAND_NO_SUBPAGE_WRITE flag. With NAND_NO_SUBPAGE_WRITE, the default routine (nand_write_page()) should perform the equivalent operations. Signed-off-by:

The TI AEMIF driver registers are used to setup timings for each chip select. The same registers range is used to setup NAND settings. The AEMIF and NAND drivers not use the same registers in this range. In case with TI AEMIF driver, the memory address range is requested already by AEMIF, so we cannot request it twice, just ioremap.

The Keystone arch has compatible nand device, so reuse it. In case with Keystone it depends on TI_AEMIF because AEMIF driver is responsible to set timings. See http://www.ti.com/lit/ug/sprugz3a/sprugz3a.pdfReviewed-by:

The properties davinci-ecc-mode, davinci-nand-use-bbt, davinci-nand-buswidth are MTD generic. Correct names for them are: nand-ecc-mode, nand-on-flash-bbt, nand-bus-width accordingly. So rename them in dts and documentation. Reviewed-by:
