From 732b5a44a0a032da5ebb775b5df2ee2a36af988f Mon Sep 17 00:00:00 2001

Subject: [PATCH] MicroBlaze fix mask for barrel shift instructions
As of v10.0 the bsi (bslli/bsrai/bsrli/bsefi/bsifi) instructions have
bits 16 and 17 defined as 'Insert' and 'Extract' respectively to support
bit field insert/extract operations. For the bslli/bsrai/bsrli
instructions these bits must be 0, as such update the opcode mask so
that the bslli/bsrai/bsrli instructions do not also match the bsefi and
bsifi instructions.
