2006-05-23[MTD] NAND modularize ECCThomas Gleixner1-30/+33
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 <[email protected]>
2006-05-23[MTD] NAND consolidate data typesThomas Gleixner1-11/+11

2006-05-23[MTD] Simplify NAND lockingThomas Gleixner1-3/+4
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 <[email protected]>
2006-05-22[MTD] Introduce writesizeJoern Engel1-2/+5
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 <[email protected]>

2006-05-12OneNAND: One-Time Programmable (OTP) supportKyungmin Park2-0/+10
One Block of the NAND Flash Array memory is reserved as a One-Time Programmable Block memory area. Also, 1st Block of NAND Flash Array can be used as OTP. The OTP block can be read, programmed and locked using the same operations as any other NAND Flash Array memory block. OTP block cannot be erased. OTP block is fully-guaranteed to be a valid block.

2006-05-07[MTD] Convert physmap to platform driverLennert Buytenhek1-13/+8
After dwmw2 let me know it ought to be done, I rewrote the physmap map driver to be a platform driver. I know zilch about the driver model, so I probably botched it in some way, but I've done some tests on an ixp23xx board which uses physmap, and it all seems to work. In order to not break existing physmap users, I've added some compat code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN is defined and != 0. Also, I've changed the default value for CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently compile in physmap (or new, platform-style, users of physmap) don't get burned. This works pretty well -- the new physmap driver is a drop-in replacement for the old one, and works on said ixp23xx board without any code changes needed. (This should hold as long as users don't touch 'physmap_map' directly.) Once all physmap users have been converted to instantiate their own platform devices, the compat code can go. (Or we decide that we can change all the in-tree users at the same time, and never merge the compat code.)

2005-11-29[MTD] CFI: Use 16-bit access to autoselect/read device id dataTodd Poynor1-1/+17
Recent models of Intel/Sharp and Spansion CFI flash now have significant bits in the upper byte of device ID codes, read via what Spansion calls "autoselect" and Intel calls "read device identifier". Currently these values are truncated to the low 8 bits in the mtd data structures, as all CFI read query info has previously been read one byte at a time. Add a new method for reading 16-bit info, currently just manufacturer and device codes; datasheets hint at future uses for upper bytes in other fields.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering2-2/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2005-10-30[PATCH] fix missing includesTim Schmielau1-0/+3
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round. Signed-off-by: Tim Schmielau <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2005-06-29[MTD] NAND: Reorganize chip lockingThomas Gleixner1-1/+4
The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <[email protected]>
