* mtd: replace DEBUG() with pr_debug()Brian Norris2011-09-116-54/+51
| | | | | | | | | | | | | | Start moving away from the MTD_DEBUG_LEVEL messages. The dynamic debugging feature is a generic kernel feature that provides more flexibility. (See Documentation/dynamic-debug-howto.txt) Also fix some punctuation, indentation, and capitalization that went along with the affected lines.

* mtd: nand: convert printk() to pr_*()Brian Norris2011-09-112-39/+39
| | | | | | | | | | | | | Instead of directly calling printk, it's simpler to use the built-in pr_* functions. This shortens code and allows easy customization through the definition of a pr_fmt() macro (not used currently). Ideally, we could implement much of this with dev_* functions, but the MTD subsystem does not necessarily register all its master `mtd_info.dev` device, so we cannot use dev_* consistently.

* mtd: nand: change KERN_DEBUG to KERN_INFOBrian Norris2011-09-111-7/+7
| | | | | | | | | | | | Soon we will change many printk statements into pr_* statements, i.e., 'printk(KERN_INFO, ...)' becomes 'pr_info(...)'. However, this means that KERN_DEBUG messages will become pr_debug() statements and therefore will not be activated by default - they must be enabled using dynamic debug. So, for important DEBUG messages, we will simply upgrade these to INFO so that they appear by default.

* mtd: pxa3xx_nand: enable multiple chip select supportLei Wen2011-09-111-50/+123
| | | | | | | | | | | | | | | Current pxa3xx_nand controller has two chip select which both be workable. This patch enable this feature. Update platform driver to support this feature. Another notice should be taken that: When you want to use this feature, you should not enable the keep configuration feature, for two chip select could be attached with different nand chip. The different page size and timing requirement make the keep configuration impossible. Signed-off-by: Lei Wen <leiwen@marvell.com>

* mtd: eLBC NAND: remove elbc_fcm_ctrl->oob_poiMike Hench2011-09-111-31/+2
| | | | | | | | | | | The eLBC NAND driver currently follows up each program/write operation with a read-back of the page, in order to [ostensibly] fill in ECC data for the caller. However, the page address used for this read is always -1, so the read will never work correctly. Remove this useless (and potentially problematic) block of code. Signed-off-by: Matthew L.

* mtd: nand: ignore ECC errors for simple BBM scansBrian Norris2011-09-111-3/+10
| | | | | | | | | | | | Now that nand_do_readoob() may return -EUCLEAN or -EBADMSG on ECC errors, we need to handle the return value specially in some cases. When scanning for simple bad block markers, reacting to an ECC error is not very useful, as we assume that the relevant markers are still non-0xFF for true bad blocks.

* mtd: nand: handle ECC errors in OOBBrian Norris2011-09-111-1/+8
| | | | | | | | | | | | | | | | | While the standard NAND OOB functions do not do ECC on the spare area, it is possible for a driver to supply its own OOB ECC functions (e.g., HW ECC). nand_do_read_oob should act like nand_do_read_ops in checking the ECC stats and returning -EBADMSG or -EUCLEAN on uncorrectable errors or correctable bitflips, respectively. These error codes could be used in flash-based BBT code or in YAFFS, for example. Doing this, however, messes with the behavior of mtd_do_readoob. Now, mtd_do_readoob should check whether we had -EUCLEAN or -EBADMSG errors and discard those as "non-fatal" so that the ioctls can still succeed with (possibly uncorrected) data.

* mtd: nand_base: always initialise oob_poi before writing OOB dataTHOMSON, Adam (Adam)2011-09-111-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In nand_do_write_ops() code it is possible for a caller to provide ops.oobbuf populated and ops.mode == MTD_OOB_AUTO, which currently means that the chip->oob_poi buffer isn't initialised to all 0xFF. The nand_fill_oob() method then carries out the task of copying the provided OOB data to oob_poi, but with MTD_OOB_AUTO it skips areas marked as unavailable by the layout struct, including the bad block marker bytes. An example of this causing issues is when the last OOB data read was from the start of a bad block where the markers are not 0xFF, and the caller wishes to write new OOB data at the beginning of another block. In this scenario the caller would provide OOB data, but nand_fill_oob() would skip the bad block marker bytes in oob_poi before copying the OOB data provided by the caller. This means that when the OOB data is written back to NAND, the block is inadvertently marked as bad without the caller knowing. This has been witnessed when using YAFFS2 where tags are stored in the OOB. To avoid this oob_poi is always initialised to 0xFF to make sure no left over data is inadvertently written back to the OOB area.
