[U-Boot-Users] [PATCH 4/7 v6] USB: Add support for OHCI controller on S3C6400
Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.
