* mtd: onenand: convert to mtd_device_register()Jamie Iles2011-05-251-1/+0
| | | | | | | | | | Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS preprocessor conditionals as partitioning is always available.

* mtd: onenand: make onenand/generic.c more genericMagnus Damm2009-09-191-1/+0
| | | | | | | | | | | | | | | | | | | | | Remove the ARM dependency from the generic "onenand" platform device driver. This change makes the driver useful for other architectures as well. Needed for the SuperH kfr2r09 board. Apart from the obvious Kconfig bits, the most important change is the move away from ARM specific includes and platform data. Together with this change the only in-tree board code gets an update, and the driver name is also changed gracefully break potential out of tree drivers. The driver is also updated to allow NULL as platform data together with a few changes to make use of resource_size() and dev_name().

* mtd: onenand: select MTD_PARTITIONSPaul Mundt2009-09-041-1/+1
| | | | | | | | | | | | | All of the onenand drivers depend on mtd partition support being compiled in, so just select it. Fixes up build breakage: drivers/built-in.o: In function `generic_onenand_remove': generic.c:(.devexit.text+0x80): undefined reference to `del_mtd_partitions' Reported-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* [MTD] [OneNAND] Add OMAP2 / OMAP3 OneNAND driverAdrian Hunter2008-08-121-0/+7
| | | | | | | | | | | This driver had resided in the OMAP tree but is now to be in MTD.

* [MTD] dataflash OTP supportDavid Brownell2008-08-011-0/+1
| | | | | | | | | | | | | | | Now that we can tell when we have one of the newer DataFlash chips, optionally expose the 128 bytes of OTP memory they provide. Tested on at45db642 revision B and D chips. Switch mtdchar over to a generic HAVE_MTD_OTP flag instead of adding another #ifdef for each type of chip whose driver has OTP support.

* [MTD] OneNAND Simulator supportKyungmin Park2007-06-301-0/+7
| | | | | | | | | | | | This simulate various OneNAND flash chips for the MTD onenand layer. It's simple implementation, only basic operations. It don't support the recent changes in NANDSIM such as lazy block allocation, bitflip, and so on. Note: This passed nand-tests.

* [MTD] [OneNAND] 2X program supportKyungmin Park2007-06-301-0/+16
| | | | | | | | | | | | | | | | | | | The 2X Program is an extension of Program Operation. Since the device is equipped with two DataRAMs, and two-plane NAND Flash memory array, these two component enables simultaneous program of 4KiB. Plane1 has only even blocks such as block0, block2, block4 while Plane2 has only odd blocks such as block1, block3, block5. So MTD regards it as 4KiB page size and 256KiB block size Now the following chips support it. (KFXXX16Q2M) Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M, Mux: KFM2G16Q2M, KFN4G16Q2M, And more recent chips Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* OneNAND: One-Time Programmable (OTP) supportKyungmin Park2006-05-121-0/+14
| | | | | | | | | | | | | | 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.
