From 260ba47599729a7cb2f104c437c909e8109aa2d2 Mon Sep 17 00:00:00 2001 From: bz Date: Sat, 22 Mar 2014 13:06:32 +0000 Subject: For BERI on NetFPGA assume HZ=100 by default. Remove the uart support in favour of a "jtag-uart" interface imitation providing a much simpler interface, directly exported to the host, allowing the toolchain to be shared with BERI on Altera.
