The other choice is cache invalidation and flushing around all the code that
touches ED's and TD's. This might not be too bad if it is encapsulated in
_read and _write macros. How performance critical is the ED and TD code?
The latest ARM -NP patches work on SA1110 with the SA1111 controller (which
is OHCI-like). With minimal tweaks they work on SA110/Footbridge with an
OHCI controller. We will be submitting these patches as tweaks. It's not
beautiful, but it doesn't change the mainstream (x86) code significantly.
