The current wait loop just reads the status 10000 times, which makes the

Hmmm...
Is 100ms part of the spec? I like the idea of making the timeout more
time-based, but it seems to me that this changes the timeout quite
significantly. If it took N ms before, it now takes N + 100 ms.
I think, if we want the timeout to be ~100ms, we should use a udelay
of 100 or 1000, and then reduce "retry" accordingly.
Hi,
As I said in the mail preceding this patch, I don't know what the
timeout should be. Maybe someone with a better knowledge on MMC could
come forward.
