svn commit: r263632 - in head/sys: boot/fdt/dts/mips mips/conf

[Bjoern A. Zeeb]

Author: bz
Date: Sat Mar 22 13:06:32 2014
New Revision: 263632
URL: http://svnweb.freebsd.org/changeset/base/263632

Log:
  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. [1]
