| | * | | | mtd: OneNAND: OMAP2: increase multiblock erase verify timeoutRoman Tereshonkov2011-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current multiblock erase verify read timeout 100us is the maximum for none-error case. If errors happen during multibock erase then the specification recommends to run multiblock erase verify command with maximum timeout 10ms (see specs. for KFM4G16Q2A and KFN8G16Q2A). For the most common non-error case we wait 100us in udelay polling loop. In case of timeout the interrupt mode is used to wait for the command end.

| | * | | | omap3: nand: making ecc layout as compatible with romcode eccSukumar Ghorai2011-02-17

So as to have in sync with ecc layout throughout; i.e. x-loader, u-boot and kernel. This enables to flash x-loader, u-boot, kernel, FS images from kernel itself and compatiable with other tools. This patch does not enables this feature by default and need to pass from board file to enable for any board.

It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board drivers, and a new Kconfig option to enable BCH support. It relies on the generic BCH library introduced in a previous patch. When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required error correction capability. See nand_bch_init() documentation for details. It has been tested on the following platforms using mtd-utils, UBI and UBIFS: x86 (with nandsim), arm926ejs.

* | | | mtd: NOR flash driver for OMAP-L137/AM17xDavid Griego2011-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP-L137/AM17x has limited number of dedicated EMIFA address pins, enough to interface directly to an SDRAM. If a device such as an asynchronous flash needs to be attached to the EMIFA, then either GPIO pins or a chip select may be used to control the flash device's upper address lines. This patch adds support for the NOR flash on the OMAP-L137/ AM17x user interface daughter board using the latch-addr-flash MTD mapping driver which allows flashes to be partially physically addressed. The upper address lines are set by a board specific code which is a separate patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a driver for allowing an mtd device to be used as a block device for swapping. The block device is volatile, and the mapping of swapped pages is not stored on flash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new background method into mtd_blktrans_ops, add background support into mtd_blktrans_thread(), and add mtd_blktrans_cease_background(). If the mtd blktrans dev has the background support, the thread will call background function when the request queue becomes empty. The background operation may run as long as needs to until mtd_blktrans_cease_background() tells to stop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default mtd_speedtest uses all the eraseblocks of the MTD partition being tested. For large partitions a smaller number is sufficient and makes running the test quicker. For that reason, add a parameter 'count' to specify the maximum number of eraseblocks to use for testing.
