Hi, I am porting USB OHCI driver to a custom PowerPC 405 based platform with no PCI Bus. I have taken SA1111 as a reference. USB uses DMA for its memory transfers. How can I check proper functioning of DMA. Any help/suggestion will be highly appreciated. Thankyou, regards, Nageswari ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
