linux-yocto: collie: MTD: disable erase suspend on write
Try to fix frequent errors like:
sa1100: Chip not ready for buffer write. Xstatus = 80808080, status = 80808080
0x80 = 01010000 so the bits are SR4 and SR6
SR4 = Error in (page buffer) program or OTP program (PBPOPS)
SR6 = Block erase suspended (BESS)
Now with the fixup the msg is:
SR.4 or SR.5 bits set in buffer write (status ffffffff). Clearing.
