I'm trying to write a driver for the OXU210 PCI evaluation board,
integrating it into the EHCI subsystem (see the patch below). It's still
WIP, for now only the SPH host controller is supported (no OTG).
Because this host controller can only access its own small SRAM area I'm
using the HCD_LOCAL_MEM flag and dma_declare_coherent_memory() to
enforce "local" memory utilization.
The first issue I've found is that the controller seems to have problems
with unaliged memory accesses, so I applied a patch to the core HCD code
to remove the put/get_unaligned() stuff.
After that something started to work, devices (mass storage,
usbs-serial, keyboard devices, etc.) are correctly recognized, but
there're still some issues.
More exactly, bulk transfers don't seem to complete successfully very
often. For example when I connect a USB drive I get this from dmesg:
