2012-03-26mtd: flash drivers set ecc strengthMike Dunn
Flash device drivers initialize 'ecc_strength' in struct mtd_info, which is the maximum number of bit errors that can be corrected in one writesize region. Drivers using the nand interface intitialize 'strength' in struct nand_ecc_ctrl, which is the maximum number of bit errors that can be corrected in one ecc step. Nand infrastructure code translates this to 'ecc_strength'. Also for nand drivers, the nand infrastructure code sets ecc.strength for ecc modes NAND_ECC_SOFT, NAND_ECC_SOFT_BCH, and NAND_ECC_NONE. It is set in the driver for all other modes.

2011-09-11mtd: replace DEBUG() with pr_debug()Brian Norris
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.

2008-06-04MTD/JFFS2: remove CVS keywordsAdrian Bunk
Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2008-04-22[MTD] [NAND] fix possible Ooops in rfc_from4Sebastian Siewior
I found this while I was looking how the rs_lib is working. The rs_decoder is initialized _after_ the nand core code read the BBT table and _after_ the partition table has been added. The driver has a private BBT description which is in located in flash data so we Ooops if there is a bit flip _or_ if a bit flips while reading the partition table. This patch moves the initialization of the rs_lib before the first possible access by nand core.

2006-05-23[MTD] Refactor NAND hwcontrol to cmd_ctrlThomas Gleixner
The hwcontrol function enforced a step by step state machine for any kind of hardware chip access. Let the hardware driver know which control bits are set and inform it about a change of the control lines. Let the hardware driver write out the command and address bytes directly. This gives a peformance advantage for address bus controlled chips and simplifies the quirks in the hardware drivers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

ICC likes to complain about storage class not being first, GCC doesn't care much (except for cases like "inline static"). have a hard time seeing how it could break anything. Thanks to Gabriel A.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
