Hi Ikegami,
I have seen a case myself where a value was written, chip changed
state to "ready" but when I was reading the value was incorrect.
This can happen as result of intermittent issue with flash. It is
hard to fall into scenario when testing on limited number of devices
but with large

In function do_write_buffer(), in the for loop, there is a case
chip_ready() returns 1 while chip_good() returns 0, so it never
break the loop.
To fix this, chip_good() is enough and it should timeout if it stay
bad for a while.
