* P4080/eLBC: Make Freescale elbc interrupt common to elbc devicesRoy Zang2010-10-251-0/+1
| | | | | | | | | | | | | | | | | | Move Freescale elbc interrupt from nand driver to elbc driver. Then all elbc devices can use the interrupt instead of ONLY nand. For former nand driver, it had the two functions: 1. detecting nand flash partitions; 2. registering elbc interrupt. Now, second function is removed to fsl_lbc.c.

* mtd: pxa3xx_nand: condense the flash definitionLei Wen2010-10-241-7/+0
| | | | | | | | | | | | | | | | Adding a new flash definition would need less code. Keep the platform passing flash definition method. If one flash is both defined in platform data and builtin table, driver would select the one from platform data first. By this way, platform could select the timing most suit for itself, not need to follow the common settings.

This reader is a part of larger mulifunction chip and found at least in R5C832 Driver is complete, but bewere of the fact that some (probably only type M) xD cards are 'fake' which means that they have an on board CPU and expose emulated nand command set These cards don't even store the oob area on the flash, but generate it on the fly from something else. Thus they demand to have proper values written in the oob area, and therefore only useful with SmartMedia FTL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a device driver for the NAND flash controller found on the various DaVinci family chips. It handles up to four SoC chipselects, and some flavors of secondary chipselect (e.g. based on upper bits of the address bus) as used with some multichip packages. (Including the 2 GiB chips used on some TI devel boards.) The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as available on chips like the DM355 or OMAP-L137 and needed with the more error-prone MLC NAND chips. This is a cleaned-up version of code that's been in use for several years now; sanity checked with the new drivers/mtd/tests.

This also cleans up a few spurious references to X86_PC in the driver space - those certainly should be X86. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | x86: rename X86_GENERICARCH to X86_32_NON_STANDARDIngo Molnar2009-01-291-1/+1
|/ | | | | | | | | X86_GENERICARCH is a misnomer - it contains non-PC 32-bit architectures that are not included in the default build. Rename it to X86_32_NON_STANDARD. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* [MTD] [NAND] ndfc driverSean MacLennan2009-01-051-0/+7
| | | | | | | | | | | | | | | | | 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.
