Fix fairly sad NOR-specific bug - during FS building ic->scan_dents isn't zero, but jffs2_mark_node_obsolete() migt be called it tries to finde the ic corresponding to ref - this requires ic->scan_dents = 0. Signed-off-by:

This driver does not have as many options but it's easier to maintain. And, it turns out AMD never shipped boards with different flash densities. Signed-off-by:

Check timeout while we wait for the command to finish. No worry about a false result. This prevents deadlocking when detecting an unknown number of chips and is useful for removable media too. Signed-off-by:

The change to the generic probe to look for the smallest width of chip first is causing some problems on boards with a single 16bit device. The problem seems to be the jedec_match() is truncating the device-id read from the table to match against the one read from the hardware, causing a match against the partial id of some chips with 16bit IDs (such as the SST39LF160) This fixes things for my own board, but something may need to be done if the same problem is exhibited for chips with an 8bit ID Signed-off-by:

When scanning NAND for bad blocks, don't read the whole page, read only needed OOB bytes instead. Also check the return code of the nand_read_raw() function. Correctly free the this->bbt array in case of failure. Tested with Large page NAND. Fix debugging message. Signed-off-by:

This patch replaces the current CONFIG_JFFS2_FS_NAND, CONFIG_JFFS2_FS_NOR_ECC and CONFIG_JFFS2_FS_DATAFLASH with a single configuration option - CONFIG_JFFS2_FS_WRITEBUFFER. The only functional change of this patch is that the slower div/mod calculations for SECTOR_ADDR(), PAGE_DIV() and PAGE_MOD() are now always used when CONFIG_JFFS2_FS_WRITEBUFFER is enabled.

For Dataflash, can_mark_obsolete = false and the NAND write buffering code (wbuf.c) is used. Since the DataFlash chip will automatically erase pages when writing, the cleanmarkers are not needed - so cleanmarker_oob = false and cleanmarker_size = 0 DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). The SECTOR_ADDR macro (added in the previous core patch) is replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is selected. Signed-off-by:

DataFlash page-sizes are not a power of two (they're multiples of 528 bytes). There are a few places in JFFS2 code where sector_size is used as a bitmask. A new macro (SECTOR_ADDR) was defined to calculate these sector addresses. For non-DataFlash devices, the original (faster) bitmask operation is still used. In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024. Since this could be larger than the sector size of the DataFlash, this is now basically set to MIN(sector_size, 1024). Addition of a jffs2_is_writebuffered() macro. Signed-off-by:

This is implemented using a ioctl to switch the MTD char device into one of the different OTP "modes", at which point read/write/seek can operate on the selected OTP area. Also some extra ioctls to query for size and lock protection segments or groups. Some example user space utilities are provided. Signed-off-by:

This enables support for reading, writing and locking so called "Protection Registers" present on some flash chips. A subset of them are pre-programmed at the factory with a unique set of values. The rest is user-programmable. Signed-off-by:
