2010-08-06mxc_nand: make some internally used functions overwriteableSascha Hauer
This patch prepares the driver to add v3 controller support later. The v3 controller is basically the same controller as v1 and v2, but with a completely different register layout. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-08-06mxc_nand: rework get_dev_statusSascha Hauer
We save/restore the value in the buffer anyway, so it makes no difference whether we use main_area0 or main_area1. So, we can use main_area0 and remove main_area1 from the driver which is otherwise unused. Also, clean up the comments in get_dev_status.

2010-08-05mtd: Blackfin NFC: fix nand busy detectionBarry Song
The IRQSTAT register is a W1C register used by the interrupt handler and may have its BUSY bit changed. This makes it somewhat unreliable for the polling devready function. So switch it over to use the BUSY bit in the STAT register that always reflects the current state of the hardware. This fixes driver hangs seen when the NAND flash is under heavy system load (like I/O benchmarks).

2010-08-05mtd: Blackfin NFC: fix handling of page sizesBarry Song
Rather than forcing the platform resources to declare the desired page size, simply use the existing information passed down to us by the higher layers.

2010-08-05mtd: Blackfin NFC: wait for the ECC reset to finishBarry Song

2010-08-05mtd: Blackfin NFC: fix raw page write/read handlingBarry Song
Our write_buf/read_buf funcs always do ECC in HW ECC mode. That is not needed for raw funcs. In fact, write_buf/read_buf should be a pure func for data input/output while chip->ecc.hwctl controls ECC. Unfortunately, we can't separate ECC from normal data input/output in our NFC, so our DMA write_buf/read_buf entries are coupled with ECC operations closely. Thus we need to provide dedicated read_page_raw/write_page_raw funcs where we do non-DMA transactions so as to avoid automatic ECC.

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.

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).
