* [MTD] [NAND] ndfc driverSean MacLennan2009-01-05
| | | | | | | | | | | | | | | | | The current ndfc driver only compiles under arch/ppc. This arch was removed from the kernel. I notice the event entry for the ndfc in Kconfig has been removed in 2.6.28. This patch converts the ndfc to a proper OF (OpenFirmware) driver. I can give a working example of the DTS if needed. The patch has been in production use on the PIKA Warp Appliance and is in use by others. The Warp basically boots from NAND, so the ndfc driver is very important to us.

* [MTD] [NAND] pxa3xx: fix non-page-aligned readsMatt Reimer2009-01-05
| | | | | | | | | | | | | | | | | Reads from non-page-aligned addresses were broken because while the address to read from was correctly written to NDCB*, a full page was always read. Fix this by ignoring the column and only using the page address. I suspect this whole-page behavior is due to the controller's need to read the entire page in order to generate correct ECC. In the non-ECC case this could be optimized to use the column address, and to set the read length to what is being requested rather than the length of an entire page.

This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* | | MTD: nandsim: use less RAMAlexey Korolev2008-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nandsim consumes ~2x more RAM than the density of simulated device. It becomes critical if we need to simulate 256MB NAND and run stress tests on it. We investigated the reasons. nandsim allocates space for pages using kmalloc function. The size of LP nand page is 2112 bytes. kmalloc gets space from slab pools by chunks 2^n. So if we need to kmalloc 2112 bytes, 4096 bytes will be consumed by system. The best way to avoid this issue would be using kmem_cache allocations. AFAIK this mechanism specially designed to handle cases when arrays of allocations are used.

| * [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly writtenRichard Genoud2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions that write the OOB info (on hardware ECC only) use the HW_SYNDROME method. This is not correct : the start position is "pos = eccsize + chunk" and should be eccsize. So, the standard (nand_write_oob_std) function should be used. This patch corrects this by using NAND_ECC_HW instead of NAND_ECC_HW_SYNDROME. This has only been tested on small pages nand flash. (if anyone can test it on large pages that would be great). kernel version : 2.6.27-rc2 (current git mtd-2.6) Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| * [MTD] [NAND] remove dead Kconfig associated with !CONFIG_PPC_MERGEKumar Gala2008-10-10
| | | | | | | | | | | | | | | | | | | | | | | | Removed the Kconfig associated with 'NDFC NanD Flash Controller'. We can't enable !CONFIG_PPC_MERGE so there is no way to enable this. Additionally the code needs to get updated for arch/powerpc. For the time being lets just remove the Kconfig option so we can actually remove CONFIG_PPC_MERGE.

| * [MTD] [NAND] driver extension to support NAND on TQM85xx modulesWolfgang Grandegger2008-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the FSL UPM NAND driver from Anton Vorontsov to support hardware which does not have the R/B pin of the NAND chip connected, like the TQM8548 module: - The OF_GPIO dependency has been removed from the Kconfig option because GPIO is not needed. The relevant gpio_* function are then stubbed out in <linux/gpio.h>. - It re-introduces the chip-delay property to define an appropriate maximum delay time (tR) required for read operations. The binding will be documented in a separate patch. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
| * [MTD] [NAND] fsl_upm: update driver for the new OF bindingsAnton Vorontsov2008-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't chip-specific, and we should always do waits. I saw one board that didn't need fsl,wait-pattern, but I assume this was the exception that proves the rule; - Get rid of chip-delay. Today there are no users for this, and if anyone really need this they should push the OF bindings beforehand; - Now flash chips should be child nodes of the FSL UPM NAND controller; - Implement OF partition parsing.
