2006-05-30[MTD] Disconnect struct mtd_info from ABIJoern Engel1-1/+10
mtdchar.c direcly copied part of struct mtd_info to userspace, thereby implicitly making it part of the ABI. With this patch, struct mtd_info is independent of the ABI and can have its fields removed, reordered, etc. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2006-05-30[MTD] replace MTD_RAM with MTD_GENERIC_TYPEJoern Engel8-8/+8

2006-05-30[MTD] NAND Expose the new raw mode function and status info to userspaceThomas Gleixner5-87/+232
The raw read/write access to NAND (without ECC) has been changed in the NAND rework. Expose the new way - setting the file mode via ioctl - to userspace. Also allow to read out the ecc statistics information so userspace tools can see that bitflips happened and whether errors where correctable or not. Also expose the number of bad blocks for the partition, so nandwrite can check if the data fits into the parition before writing to it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-29[MTD] NAND Signal that a bitflip was corrected by ECCThomas Gleixner5-9/+29
Return -EUCLEAN on read when a bitflip was detected and corrected, so the clients can react and eventually copy the affected block to a spare one. Make all in kernel users aware of the change. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-29[MTD] Rework the out of band handling completelyThomas Gleixner14-468/+859
Hopefully the last iteration on this! The handling of out of band data on NAND was accompanied by tons of fruitless discussions and halfarsed patches to make it work for a particular problem. Sufficiently annoyed by I all those "I know it better" mails and the resonable amount of discarded "it solves my problem" patches, I finally decided to go for the big rework. After removing the _ecc variants of mtd read/write functions the solution to satisfy the various requirements was to refactor the read/write _oob functions in mtd. The major change is that read/write_oob now takes a pointer to an operation descriptor structure "struct mtd_oob_ops".instead of having a function with at least seven arguments. read/write_oob which should probably renamed to a more descriptive name, can do the following tasks: - read/write out of band data - read/write data content and out of band data - read/write raw data content and out of band data (ecc disabled) struct mtd_oob_ops has a mode field, which determines the oob handling mode. Aside of the MTD_OOB_RAW mode, which is intended to be especially for diagnostic purposes and some internal functions e.g. bad block table creation, the other two modes are for mtd clients: MTD_OOB_PLACE puts/gets the given oob data exactly to/from the place which is described by the ooboffs and ooblen fields of the mtd_oob_ops strcuture. It's up to the caller to make sure that the byte positions are not used by the ECC placement algorithms. MTD_OOB_AUTO puts/gets the given oob data automaticaly to/from the places in the out of band area which are described by the oobfree tuples in the ecclayout data structre which is associated to the devicee. The decision whether data plus oob or oob only handling is done depends on the setting of the datbuf member of the data structure. When datbuf == NULL then the internal read/write_oob functions are selected, otherwise the read/write data routines are invoked. Tested on a few platforms with all variants. Please be aware of possible regressions for your particular device / application scenario Disclaimer: Any whining will be ignored from those who just contributed "hot air blurb" and never sat down to tackle the underlying problem of the mess in the NAND driver grown over time and the big chunk of work to fix up the existing users. The problem was not the holiness of the existing MTD interfaces. The problems was the lack of time to go for the big overhaul. It's easy to add more mess to the existing one, but it takes alot of effort to go for a real solution. Improvements and bugfixes are welcome! Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-29[MTD] Remove silly MTD_WRITE/READ macrosThomas Gleixner7-157/+186

2006-05-29[MTD] NAND Replace oobinfo by ecclayoutThomas Gleixner10-44/+74

2006-05-29[MTD] NAND Consolidate oobinfo handlingThomas Gleixner5-24/+6
