2006-05-29[MTD] NAND Fix platform structure and NDFC driverThomas Gleixner1-4/+2
The platform structure was lacking an oobinfo field. The NDFC driver had some remains from another tree. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-29[MTD] Fix debug printk format warning in m25p80 SPI chip driver, again.Andrew Morton1-1/+1

2006-05-29[MTD] AMD Geode NAND support can depend on X86_32; we won't see it on x86_64David Woodhouse1-1/+1
Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-27[MTD] NAND Consolidate references and add back default name settingThomas Gleixner1-7/+10
We have a type pointer. Make use of it instead of the error prone nand_ids[i] reference. The NAND driver used to set default name settings from the chip ID string for the device. The feature got lost during the rework. Add it back. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-27[MTD] NAND simplify nand_chip_selectThomas Gleixner1-2/+0
nCE setting can be done when the first command is issued to the device. We keep the deselect functionality as it makes sense to deassert nCE when the device becomes idle. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2006-05-26[MTD] NAND modularize write functionThomas Gleixner6-522/+263
Modularize the write function and reorganaize the internal buffer management. Remove obsolete chip options and fixup all affected users. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-26[MTD] Remove PCI dependency for Geode CS553[56] NAND controller.David Woodhouse2-4/+31
PCI is faked on these devices by SMM traps. Don't depend on that -- check for the chipset directly instead. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-25[MTD] Fix NAND_VERIFY_WRITE case to build with tglx's recent changesDavid Woodhouse1-4/+4
Bad tglx. No biscuit. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-25[MTD] Remove the only useless readv implementationThomas Gleixner2-33/+0
Removing readv from struct mtd_info broke block2mtd. Remove the reference and the useless default implementation. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND Modularize read functionThomas Gleixner3-247/+267
Split the core of the read function out and implement seperate handling functions for software and hardware ECC. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND Cleanup oob functionsThomas Gleixner1-75/+81
Cleanup the code in the oob related functions and make use of the new NO_READRDY flag. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND Introduce NAND_NO_READRDY optionThomas Gleixner1-77/+88
The nand driver has a superflous read ready / command delay in the read functions. This was added to handle chips which have an automatic read forward. Newer chips do not have this functionality anymore. Add this option to avoid the delay / I/O operation. Mark all large page chips with the new option flag. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND Initialize controller lock and wq only onceThomas Gleixner2-4/+9
The lock simplifying patch did not move the lock and waitqueue initialization into the controller allocation patch. This reinitializes waitqueue and spinlocks also for driver supplied controller stuctures. Move it into the allocation path. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND fix cmd_ctrl breakageThomas Gleixner1-5/+10
The cmd_ctrl rework lacks some state transition flags. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND coding style and namespace cleanupThomas Gleixner1-534/+520
Cleanup the functions which are not going to change in the next steps. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-24[MTD] NAND LED support cleanupThomas Gleixner1-2/+6
Move the define out of the middle of the code and add an appropriate comment. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-24[MTD] NAND remove write_byte/word function from nand_chipThomas Gleixner6-88/+14
The previous change of the command / hardware control allows to remove the write_byte/word functions completely, as their only user were nand_command and nand_command_lp. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-24[MTD] Refactor NAND hwcontrol to cmd_ctrlThomas Gleixner17-527/+413
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>
2006-05-24[MTD] Export nand_write_rawThomas Gleixner1-0/+1
The previous _ecc removal / cleanup broke (i)nftl module usage. Export the missing symbol. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-24[MTD] Mark NAND drivers TOTO and PPChameleon brokenThomas Gleixner1-2/+2
Both drivers can not be fixed and compiled due to missing header files. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove read/write _ecc variantsThomas Gleixner12-381/+198
MTD clients are agnostic of FLASH which needs ECC suppport. Remove the functions and fixup the callers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove readv/readv_eccThomas Gleixner3-32/+0
These functions were never implemented and added only bloat to partition and concat code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove nand writev supportThomas Gleixner5-432/+3
NAND writev(_ecc) support is not longer necessary. Remove it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2006-05-23[MTD] NAND modularize ECCThomas Gleixner15-136/+98
First step of modularizing ECC support. - Move ECC related functionality into a seperate embedded data structure - Get rid of the hardware dependend constants to simplify new ECC models Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] NAND cleanup nand_scanThomas Gleixner1-174/+233
Seperate functionality out of nand_scan so the code is more readable. No functional change. First step of simplifying the nand driver. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] NAND consolidate data typesThomas Gleixner1-53/+53
The NAND driver used a mix of unsigned char, u_char amd uint8_t data types. Consolidate to uint8_t usage Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2006-05-23[MTD] Add support for NDFC NAND controllerThomas Gleixner3-0/+324
NDFC NAND Flash controller is embedded in PPC EP44x SoCs. Add platform driver based support. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Simplify NAND lockingThomas Gleixner1-38/+43
Replace the chip lock by a the controller lock. For simple drivers a dummy controller structure is created by the scan code. This simplifies the locking algorithm in nand_get/release_chip(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Improve software ECC calculationThomas Gleixner2-134/+96
Unrolling the loops produces denser and much faster code. Add a config switch which allows to select the byte order of the resulting ecc code. The current Linux implementation has a byte swap versus the SmartMedia specification Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Introduce MTD_BIT_WRITEABLEJoern Engel4-5/+4
o Add a flag MTD_BIT_WRITEABLE for devices that allow single bits to be cleared. o Replace MTD_PROGRAM_REGIONS with a cleared MTD_BIT_WRITEABLE flag for STMicro and Intel Sibley flashes with internal ECC. Those flashes disallow clearing of single bits, unlike regular NOR flashes, so the new flag models their behaviour better. o Remove MTD_ECC. After the STMicro/Sibley merge, this flag is only set and never checked. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2006-05-23[MTD] Merge STMicro NOR_ECC code with Intel Sibley codeJoern Engel1-2/+2
In 2002, STMicro started producing NOR flashes with internal ECC protection for small blocks (8 or 16 bytes). Support for those flashes was added by me. In 2005, Intel Sibley flashes copied this strategy and Nico added support for those. Merge the code for both. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2006-05-23[MTD] Introduce writesizeJoern Engel14-108/+108
At least two flashes exists that have the concept of a minimum write unit, similar to NAND pages, but no other NAND characteristics. Therefore, rename the minimum write unit to "writesize" for all flashes, including NAND. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>

2006-05-21[MTD] Use symbol_request() in old DiskOnChip probe code to find actual driverDavid Woodhouse1-42/+5
The previous code wouldn't work correctly on architectures which have a non-empty MODULE_SYMBOL_PREFIX, and this version is neater if slightly less optimal in the built-in case. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-21[MTD] Add Amstrad Delta NAND supportJonathan McDowell3-0/+245

2006-05-17MTD: mtdconcat NAND/Sibley support (rev.2)Alexander Belyakov1-5/+164
There is a second revision of "mtdconcat NAND/Sibley" patch. I hope the patch will not get damaged as I'm posting it from gmail account, thanks to Jorn. The patch adds previously missing concat_writev(), concat_writev_ecc(), concat_block_isbad(), concat_block_markbad() functions to make concatenation layer compatible with Sibley and NAND chips. Patch has been cleared from whitespaces, fixed some lines of code as requested. Also I have added code for alignment check that should support Jorn's "writesize" patch.

In an unrelated MTD commit, a description about the ms02-nv module got removed from Kconfig. While I personally agree with this removal, the module maintainer (Maciej W. Rozycki) would like to see it added back. In the absense of any consistency regarding Kconfig descriptions his wish should be followed.
