+Subject: [PATCH 3/3] RTEMS: Add e6500 multilibs for PowerPC
+
+Use 32-bit instructions only since currently there is no demand for a
+larger address space. Provide one multilib with FPU and AltiVec support
+and one without.
+
+gcc/ChangeLog
+
+ * config/rs6000/rtems.h (CPP_OS_RTEMS_SPEC): Define __PPC_CPU_E6500__
+ for -mcpu=e6500.
+ * config/rs6000/t-rtems: Add e6500 multilibs.

+Subject: [PATCH 2/3] RTEMS: Fix MPC8540 multilibs for PowerPC
+
+GCC generates SPE instructions even if -msoft-float is specified.
+Explicitly add -mno-spe to prevent generation of SPE instructions. This
+multilib variant must not lead to a usage of the SPE.
+
+gcc/ChangeLog
+
+ * config/rs6000/t-rtems: Add -mno-spe to soft-float multilib for
+ MPC8540.
