DetailsIt is suspected that the USB functionality inside PortalPlayer chips is compatible with that of the i.MX31 provided by Freescale, but with base address 0xc5000000 instead of 0x0x43F88000. A common USB driver should therefore be used for all PortalPlayer targets.
This patch starts the process by combining USB code for all PP targets into one driver, usb-pp.c. It adds register defines for all registers available in the i.MX31 in the file usb-target.h. It uses the USB initialization and detection code from the iPod driver updated for clarity to use the defines rather than addresses. I have tested this on my iriver H10 20GB. I will be able to test on my Sansa e280 shortly too. It will also need testing on TPJ1022 and at least one iPod model.

I can confirm it compiles and appears to work fine on my ipod Color.
