+Subject: [PATCH] target-mips: add 24KEc CPU definition
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Define a new CPU definition supporting 24KEc cores, similar to
+the existing 24Kc, but with added support for DSP instructions
+and MIPS16e (and without FPU).
