Subject: Revert ehci(4) bits in the previous commit.  Apparently 64-bit DMA is broken
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=89d99141c9b38170e9d466a3db80e4c79664f34e;p=openbsd

Revert ehci(4) bits in the previous commit.  Apparently 64-bit DMA is broken
in (almost?) all ehci(4) controllers.
