* OMAP: OneNAND: fix 104MHz supportAdrian Hunter2011-02-171-0/+1
| | | | | | | | | | 104MHz needs a latency of 8 clock cycles and the VHF flag must be set. Also t_rdyo is specified as "not applicable" so pick a lower value, and force at least 1 clk between AVD High to OE Low.

* mtd: OneNAND: multiblock erase supportMika Korhonen2009-11-301-0/+2
| | | | | | | | | | | | | Add support for multiblock erase command. OneNANDs (excluding Flex-OneNAND) are capable of simultaneous erase of up to 64 eraseblocks which is much faster. This changes the erase requests for regions covering multiple eraseblocks to be performed using multiblock erase.

* mtd: Flex-OneNAND supportRohit Hagargundgi2009-06-051-2/+18
| | | | | | | | | | | | | | | | | | Add support for Samsung Flex-OneNAND devices. Flex-OneNAND combines SLC and MLC technologies into a single device. SLC area provides increased reliability and speed, suitable for storing code such as bootloader, kernel and root file system. MLC area provides high density and is suitable for storing user data. SLC and MLC regions can be configured through kernel parameter.

* [MTD] [OneNAND] 2X program supportKyungmin Park2007-06-301-0/+4
| | | | | | | | | | | | | | | | | | | 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/+8
| | | | | | | | | | | | | | 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.
