+Subject: [PATCH 31/63] [Patch, microblaze]: Add new bit-field instructions
+ This patches adds new bsefi and bsifi instructions. BSEFI- The instruction
+ shall extract a bit field from a register and place it right-adjusted in the
+ destination register. The other bits in the destination register shall be set
+ to zero BSIFI- The instruction shall insert a right-adjusted bit field from a
+ register at another position in the destination register. The rest of the
+ bits in the destination register shall be unchanged
+
