By the way, can't we shorten mount time for Intel chips by rewriting read
routines in such a way that they don't send Read Status Register command when
chip->status is FL_READY?
I think we can. Acually, I have tried already and it shortens mount time
dramatically.
So the question, as I can see it, is can we be sure that Status Register has
7th bit set when chip->status == FL_READY?
Any comments?
Nick
