From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com> This adds the necessary properties to MicroBlaze cores to enable exceptions on failed bus accesses. There's no board that acutally uses this yet. This also adds an unimplemented device to the s3adsp1800 board since I used that board to test this feature. The s3adsp1800 does not enable the exceptions by default though, so they remain off.
