CF problem on sh3 (620lx/660lx hp machines)

[Rafael I. Z. <riz...@ya...>]

Hello,
  We have not fixed a problem with CF and libata on
old sh3 hp machines (620lx and 660lx at least) which
gives us a "qc timeout" on boot time.

  I know that the patch below fixes that one,
but I don't know how we should solve that problem
in the correct way.

Any idea?
Regards
