+	  Sourcery CodeBench toolchain for the MIPS architecture, from
+	  Mentor Graphics. It uses gcc 5.3, binutils 2.25.51, glibc
+	  2.23, uClibc 0.9.30 and gdb 7.10.50, kernel headers 4.4.1. It
+	  has support for the following variants:
+	    - MIPS32r2 - Big-Endian, 2008 NaN, O32
+	      Select MIPS (big endian) core
+	      Disable BR2_SOFT_FLOAT
