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: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
