+==================== Branch work213, patch #1 ====================
+
+Add -mcpu=future support
+
+This patch adds the support that can be used in developing GCC support
+for potential future PowerPC processors.
+
+These changes are being added so that hardware designers can evaluate
+potential new features to be added to the PowerPC processors in the
+future. It may be these features will be incorporated into real
+hardware using a different name in the future. Or it may be these
+features will not be incoporated into actual PowerPC hardware in the
+future.
+
+At the moment, I have not added a new processor, and I'm using the
+power11 for tuning defaults and such. When we are ready to add new
+tuning rules a potential future processor, we will add the support for
+the new processor.
+
+I have tested these patches on both big endian and little endian
+PowerPC servers, with no regressions. Can I check these patchs into
+the trunk?
