Blackfin: nand: drain the write buffer before returning
The current Blackfin nand write function fills up the write buffer but returns before it has had a chance to drain. On faster systems, this isn't a problem as the operation finishes before the ECC registers are read, but on slower systems the ECC may be incomplete when the core tries to read it. So wait for the buffer to drain once we're done writing to it. Signed-off-by: Andrew Caldwell <Andrew.Caldwell@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
