RISC-V Updates for 3.2, Part 2
This patch set contains a handful of Michael's CSR-related cleanups,
which should allow us to proceed with more outstanding bug fixes that
depend on them.
Additionally, there is a patch that turns on USB. This works for me
when the kernel has the appropriate drivers (which will soon be in
defconfig) and I pass
-device usb-ehci
-drive id=my_usb_disk,file=usbdisk.img,if=none,format=raw
-device usb-storage,drive=my_usb_disk
to QEMU.
