It more sense to calculate such things *after* quantizing the timings with calc_mck_cycles()...
Why?
More precise result -- matching the clock being used.
However, I don't understand now why you need to stretch t9...
Ah, I do again. t0 *should be equal* to t1 + t2 + t9 for the better speeds.
Moreover, t1 + t2 + t9 must be no less that t0 minimum, otherwise it would be a timing violation.
And hold time should meet min t2i requirement, so t9 = max(t9_orig, t2i - t1).
There's no direct connection between these in ATA/CF specs.
