mtd: onenand: Store bad block marker position in chip struct

2019-04-18T06:54:07+00:00

The information about where the manufacturer puts the bad block markers inside the bad block and in the OOB data is stored in different places. Let's move this information to the chip struct, as we did it for rawnand. Signed-off-by: Frieder Schrempf Reviewed-by: Miquel Raynal Signed-off-by: Miquel Raynal

mtd: onenand: switch to mtd_ooblayout_ops

2016-05-05T21:51:49+00:00

Implementing the mtd_ooblayout_ops interface is the new way of exposing ECC/OOB layout to MTD users. Modify the onenand drivers to switch to this approach. Signed-off-by: Boris Brezillon

mtd: OneNAND: Detect the correct NOP when 4KiB pagesize

2011-09-11T12:02:13+00:00

There are two different 4KiB pagesize chips KFM4G16Q4M series have NOP 4 with version ID 0x0131 But KFM4G16Q5M has NOP 1 with versoin ID 0x013e Note that Q5M means that it has NOP 1. Signed-off-by: Kyungmin Park Signed-off-by: Artem Bityutskiy

mtd: onenand: add new option to control initial onenand unlocking

2011-03-11T14:22:47+00:00

A new option ONENAND_SKIP_INITIAL_UNLOCKING is added. This allows to disable initial onenand unlocking when the driver is initialized. Signed-off-by: Roman Tereshonkov Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: OneNAND: add enable / disable methods to onenand_chip

2011-01-06T15:34:19+00:00

Add enable / disable methods called from get_device() / release_device(). These can be used, for example, to allow the driver to prevent the voltage regulator from being put to sleep while OneNAND is in use. Signed-off-by: Adrian Hunter Signed-off-by: David Woodhouse

mtd: onenand: add option and variable for cache program feature

2010-12-03T16:27:54+00:00

A new option is added for cache program feature. A new variable ongoing is introduced for onenand_chip to handle the multi-command cache program operation. Signed-off-by: Roman Tereshonkov Acked-by: Kyungmin Park Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: OneNAND: Introduce chip_probe function

2010-08-04T09:51:47+00:00

Samsung SoCs use the own OneNAND controler and detect OneNAND chip at power on. To use this feature, introduce the chip_probe function. Also remove workaround for Samsung SoCs. Signed-off-by: Kyungmin Park Signed-off-by: David Woodhouse

mtd: onenand: add new callback for bufferram read

2010-05-14T00:50:04+00:00

This patch adds a new callback for the underlying drivers, which is called instead of accessing the buffer ram directly. This callback will be used by Samsung OneNAND driver to implement DMA transfers on S5PC110 SoC. Signed-off-by: Kyungmin Park Signed-off-by: Marek Szyprowski Signed-off-by: David Woodhouse

mtd: onenand: allocate verify buffer in the core

2010-05-14T00:49:48+00:00

This patch extends OneNAND core code with support for OneNAND verify write check. This is done by allocating the buffer for verify read directly from the core code. Signed-off-by: Kyungmin Park Signed-off-by: Marek Szyprowski Signed-off-by: David Woodhouse
