From aff2bc6dc6d839caf6df0900437cc2cc9e180605 Mon Sep 17 00:00:00 2001 From: Yongbok Kim Date: Fri, 10 Jul 2015 12:10:52 +0100 Subject: [PATCH] target-mips: update mips32r5-generic into P5600 As full specification of P5600 is available, mips32r5-generic should be renamed to P5600 and corrected as its intention. Correct PRid and detail of configuration. Features which are not currently supported are described as FIXME.
