* mtd: ubi: add API call to rename volumes.Giorgio Dal Molin2016-09-271-0/+1

* mtd: ubi: Add API calls to create/remove volumesSascha Hauer2016-09-221-0/+3
| | | | | | | | | | Currently we use a ioctl API to create/remove ubi volumes. This means we always have to carry all function code for ubi volume manipulation when the ioctl is compiled in. This adds a function API to create/remove volumes so that the linker can throw the unused code away later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mtd: nand: Enable subpage readsSascha Hauer2016-05-101-1/+1
| | | | | | | | Until now we did not support subpage reads for smaller binary sizes. Scanning UBI volumes on large page NANDs can be painfully slow, subpage reads can speed this up significantly, so enable subpage reads. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: nand: Pass page argument to read_subpage hookSascha Hauer2016-05-101-1/+1

| | | | | | | | mtd_[read|write|erase] are input functions to the mtd subsystem, so check for valid input data here rather than relying on the drivers doing this. The checks are copied from the Kernel as of 4.5-rc5 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: Make erase_info structs 64bit where necessarySascha Hauer2016-02-092-8/+8
| | | | | | | | Make the userspace structs 64bit where necessary. Since we do not have separated kernel/userspace in barebox we can just modifiy the original structs instead of adding separate 64bit structs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mtd: nand: Add erased page bitflip check helper functionsMarkus Pargmann2016-01-041-0/+5
| | | | | | | | | | This adds the bitflip check helper functions from the kernel. They are used to check for bitflips in erased pages and correct them in the buffer so that UBI can work with it. Unfortunately most nand controllers do not have ECC for erased pages and don't do this on their own.

* mtd: m25p80: make it possible to use large blocks if desiredSascha Hauer2015-08-261-1/+3
| | | | | | | | | | Some SPI NOR flashes support 4K erase blocks. 4K erase blocks do not work with UBIFS which needs a minimum erase block size of 15360 bytes. Also bigger sectors are faster to erase. This patch adds a device tree option to use the bigger blocks instead of the default 4K blocks.

* ARM: i.MX6: use generic calculation in nand bbu handlerStefan Christ2015-01-291-0/+37
| | | | | | | | | | | The parameters ECC Strength, BadBlockMarkerByte and BadBlockMarkerStartBit in the FCB structure depends on the nand chip's pagesize and oobsize. Instead of hardcoding these values into the imx6 bbu handler calculate these values on the fly. Therefore we export the necessary functions from the nand_mxs driver to use them in the bbu handler.

* mtd: nand: create bb devices automaticallySascha Hauer2014-04-281-0/+2

* mtd: Update internal API to support 64-bit device sizeDmitry Lavnikevich2014-03-122-3/+20
| | | | | | | | | | | | | | | | | | | MTD internal API presently uses 32-bit values to represent device size. This patch updates them to 64-bits but leaves the external API unchanged. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats; - division and modulus of 64-bit values (mtd_div_by_wb, mtd_div_by_eb may be used in some of such cases).

* | mtd: nand: disable subpage readsSascha Hauer2014-03-031-1/+2
|/ | | | | | | | | | | | | | The default nand_read_subpage implementation returns -ENOSUPP, so we have to make sure that barebox never uses this implementation. By setting the NAND_SUBPAGE_READ flag to 0x0 we ensure NAND_HAS_SUBPAGE_READ() never returns true and also give the compiler a chance to optimize away some unused code. subpage reads are a rather exotic feature even in Linux. It is only used on largepage NANDs with soft ecc. Even if we have this case it needs non page aligned reads to actually profit from this feature.

* mtd: Add subpagesize to mtd_info_userSascha Hauer2013-12-201-0/+1
| | | | | | | | | ubiformat needs the subpagesize to work correctly. The kernel uses sysfs to pass the subpagesize, but in barebox we have the possibility to extend struct mtd_info_user. Add a corresponding field and use it in ubiformat. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mtd: Pass device_id to add_mtd_deviceSascha Hauer2013-10-291-1/+1
| | | | | | | | | Right now we do not support persistent names for mtd devices. The base name can be passed to add_mtd_device, but this is always appended with a dynamic number. With this patch add_mtd_device takes a device_id argument which can be used to create a mtd device with an exact name. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

It is synchronized as best as we can get: - locks removed - The splitting in different files we had to better support different features has been dropped. Instead this is now done mostly with the use of __maybe_unused Some barebox adjustments are forward ported, like: - Allow partial page writes - Optionally allow to erase bad blocks - check for all_ff before writing a page Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
