Intel flashes status changes for the entire device not partition based. The only exception will be when two L18 flashes(32M each contiguous to make 64M) are used -> in which case we need to "reset to read" each devices. M18 flash does not seem supported (most probably coz io_remap address space wont give 256M) - but if it is, then we need to do the same there. The correct solution though is to fix in the cfi driver by ensuring that lock and unlock functions need to reset the device back to read mode by issuing 0xFF(reset) cmd at the end of operation. > I tested this patch on 3430, the WDT reset works fine. Please note that the patch works only because the boot device was in an invalid state, the patch merely masks the real problem and in my opinion should not be incorporated to mainline kernel - instead the root cause in mtd chip driver be fixed.
