2010-08-05mtd: denali: update get nand para functionsChuanxiao Dong1-72/+35
In denali driver, wTotalBlocks variable is useless, so just remove them in get_toshiba_nand_para and get_hynix_nand_para first. Other wTotalBlocks in denali.c and other variables in dev_info struct are also useless, will remove them later. Also add a parameter in get_hynix_nand_para to prepare to remove dev_info struct. This parameter comes by reading NAND ID directly. Reading register will report wrong value for some NAND chips, e.g. some Micron MT29F32G08QAA chips. So update NAND_CMD_READID method as well.

2010-08-05mtd: Blackfin NFC: fix nand busy detectionBarry Song1-2/+2
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 Song2-41/+48

2010-08-05mtd: Blackfin NFC: fix raw page write/read handlingBarry Song1-0/+18
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 Vorontsov1-2/+11
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 Norris3-55/+90
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 Norris2-11/+58
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).

2010-08-02mtd: mxc_nand: fix OOB accesses on i.MX27Sascha Hauer1-26/+5
The OOB handling in the mxc_nand driver is broken for v1 type controllers (i.MX27/31) with 512 byte page size. This perhaps did not show up because ubi does not use OOB. Update the driver to always read/write a whole page even if only OOB is requested. With this patch the driver passes the mtd_oobtest on i.MX27 with 512 byte page size. Also tested with 2048 byte page size and on i.MX35 (v2 type controller) Signed-off-by: Sascha Hauer <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
