Hi,
The USB OHCI driver needs to access host physical memory (to access HCCA
and endpoint descriptors). Should I just read/write directly in to the
buffer pointed to by phys_ram_base, or is there a better way?
Obviously, any I/O memory regions stuffed on the end of 'real' physical
mem won't be accessible if I just go direct to phys_ram_base, but I
doubt anyone relies on that feature...
Fabrice, what do you think?
