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: Andrew Victor Signed-off-by: Thomas Gleixner 69ؓ
