2010-08-04mtd: m25p80: Fix false-positive probingAnton Vorontsov
Since commit 18c6182bae0acca220ed6611f741034d563cd19f ("Rework probing/JEDEC code"), m25p80 driver successfully registers chips even if JEDEC probing fails. This was needed to support non-JEDEC flashes. Though, it appears that some platforms (e.g. blackfin bf533 stamp[1]) used the old behavior to detect if there's any flash connected, so the driver have to fail on JEDEC probing errors. This patch restores the old behavior for JEDEC flashes, and adds "-nonjedec" SPI device IDs for M25Pxx flashes, so that the kernel still supports non-JEDEC flashes.

The mtd layer is responsible to call mtd->{suspend,resume}.

This is an update that depends on the previous patches I sent.

2010-08-02mtd: nand: more BB Detection refactoring and dynamic scan optionsBrian Norris
This is a revision to PATCH 2/2 that I sent. Link: http://lists.infradead.org/pipermail/linux-mtd/2010-July/030911.html Added new flag for scanning of both bytes 1 and 6 of the OOB for a BB marker (instead of simply one or the other). The "check_pattern" and "check_short_pattern" functions were updated to include support for scanning the two different locations in the OOB. In order to handle increases in variety of necessary scanning patterns, I implemented dynamic memory allocation of nand_bbt_descr structs in new function 'nand_create_default_bbt_descr()'. This replaces some increasingly-unwieldy, statically-declared descriptors. It can replace several more (e.g. "flashbased" structs). However, I do not test the flashbased options personally. How this was tested: I referenced 30+ data sheets (covering 100+ parts), and I tested a selection of 10 different chips to varying degrees. Particularly, I tested the creation of bad-block descriptors and basic BB scanning on three parts: ST NAND04GW3B2D, 2K page ST NAND128W3A, 512B page Samsung K9F1G08U0A, 2K page To test these, I wrote some fake bad block markers to the flash (in OOB bytes 1, 6, and elsewhere) to see if the scanning routine would detect them properly. However, this method was somewhat limited because the driver I am using has some bugs in its OOB write functionality.

2010-08-02mtd: nand: refactor BB marker detectionBrian Norris
Some level of support for various scanning locations was already built in, but this required clean-up. First, BB marker location cannot be determined _only_ by the page size. Instead, I implemented some heuristic detection based on data sheets from various manufacturers (all found in nand_base.c:nand_get_flash_type()). Second, once these options were identified, they were not handled properly by nand_bbt.c:nand_default_bbt(). I updated the static nand_bbt_desc structs to reflect the need for more combinations of detection. The memory allocation here probably needs to be done dynamically in the very near future (see next patches).

2010-05-22drivers/mtd: Use memdup_userJulia Lawall
Use memdup_user when user data is immediately copied into the allocated region. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; position p; identifier l1,l2; @@ - to = \(kmalloc@p\|kzalloc@p\)(size,flag); + to = memdup_user(from,size); if ( - to==NULL + IS_ERR(to) || ...) { <+... when != goto l1; - -ENOMEM + PTR_ERR(to) ...+> } - if (copy_from_user(to, from, size) != 0) { - <+... when != goto l2; - -EFAULT - ...+> - } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
