Subject: [PATCH 1/3] openrisc: update SPR registers definition
Date: Wed, 21 May 2014 23:32:27 +0200	[thread overview]
Message-ID: <1400707949-16521-1-git-send-email-franck.jullien@gmail.com> (raw)

The OpenRISC architecture specification v1.0 defines
new SPR registers. This patch adds registers definition
for group 0 and update bit definitions for the CPU
configuration register.
