Hello guys,
I'm having quite some trouble getting the bmips usbs to work...
Just in case you want to take a look: https://github.com/Noltari/u-boot/commits/bmips-usb-devel https://github.com/Noltari/u-boot/commit/499d62c7871d46ac543c4c6eda3912222b8...
1) I only added support for EHCI because I haven't been able to get OHCI working... I suspect this is related to cache/v2p issues...
2) As you can see I had to *hack* ARCH_DMA_MINALIGN because otherwise usbs won't work on 6328/63268 (but they work on 6358). I'm not sure why this happens, but both 6328 and 63268 caches have 16 bytes of line size:
linux/6358: [ 0.000000] Primary instruction cache 16kB, VIPT, 2-way, linesize 16 bytes. [ 0.000000] Primary data cache 16kB, 2-way, VIPT, cache aliases, linesize 16 bytes
linux/6328: [ 0.000000] Primary instruction cache 32kB, VIPT, 4-way, linesize 16 bytes. [ 0.000000] Primary data cache 32kB, 2-way, VIPT, cache aliases, linesize 16 bytes
linux/63268: [ 0.000000] Primary instruction cache 64kB, VIPT, 4-way, linesize 16 bytes. [ 0.000000] Primary data cache 32kB, 2-way, VIPT, cache aliases, linesize 16 bytes
3) When I try to reset/stop+start usb it just fails and I don't know why, since usb start doesn't fail at all... VR-3032u # usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 2 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found

Thanks in advance for any help you can provide.
