2009-01-05[MTD] [NAND] ndfc driverSean MacLennan2-136/+140
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.

2009-01-05[MTD] [NAND] pxa3xx: fix non-page-aligned readsMatt Reimer1-2/+2
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.

2008-12-10[MTD] update internal API to support 64-bit device sizeAdrian Hunter2-25/+30
MTD internal API presently uses 32-bit values to represent device size. 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>
2008-12-10MTD: nandsim: use less RAMAlexey Korolev1-7/+18
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.

2008-10-10[MTD] [NAND] driver extension to support NAND on TQM85xx modulesWolfgang Grandegger2-5/+14
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>
