2015-01-09mtd: nand: do not scan BBT after scrubMasahiro Yamada
Currently, "nand scrub" runs chip->scan_bbt at the end of nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set. It violates the intention of NAND_SKIP_BBTSCAN. Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set. Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt() right after scrub. We can be lazier here because the BBT is scanned at the next call of nand_block_checkbad().

2015-01-09mtd: nand: Mark the BBT as scanned prior to calling scan_bbt againMasahiro Yamada
Commit 35c204d8a9d0 (nand: reinstate lazy bad block scanning) broke NAND_BBT_USE_FLASH feature. Its git-log claimed that it reinstated the change as by commit fb49454b1b6c ("nand: reinstate lazy bad block scanning"), but it moved "chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);". It causes recursion if scan_bbt does not find a flash based BBT and tries to write one, and the attempt to erase the BBT area causes a bad block check. Reinstate commit ff49ea8977b5 (NAND: Mark the BBT as scanned prior to calling scan_bbt.).

2015-01-05mtd: nand: omap_gpmc: fix error handlingGuido Martínez
"err" was an unsigned variable, causing negative error codes to turn into positive values, which are interpreted as an amount of succesfully corrected bitflips (and thus not an error). In particular, this resulted in that if the elm reports uncorrectable errors (-EBADMSG), the MTD layer (and UBI) falsely succeeded.

2014-11-26mtd: denali: set some registers after nand_scan_ident()Masahiro Yamada
Some but not all of implementations of the Denali NAND controller have hardware circuits to detect the device parameters such as page_size, erase_size, etc. Even on those SoCs with such hardware supported, the hardware is known to detect wrong parameters for some nasty (almost buggy) NAND devices. The device parameters detected during nand_scan_ident() are more trustworthy. This commit sets some hardware registers to mtd->pagesize, mtd->oobsize, etc. in the code between nand_scan_ident() and nand_scan_tail().

Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT.

We want the SPI flash probing feature to operate as a standard driver. Add a driver for the basic probing feature used by most boards. This will be activated by device_probe() as with any other driver. The 'sf probe' command currently keeps track of the SPI slave that it last used. This doesn't work with driver model, since some other driver or system may have probed the device and have access to it too. On the other hand, if we try to probe a device twice the second probe is a nop with driver model. Fix this by searching for the matching device, removing it, and then probing it again.
