- * able to combine mbx, fads, rpxlite, bseip, and classic into a single
- * generic 8xx as well.  The boards containing these processors are either
- * identical at the processor level (due to the high integration) or so
- * wildly different that testing _machine at run time is best replaced by
- * conditional compilation by board type (found in their respective .h file).

+ * This is currently limited to CONFIG_ALL_PPC and CHRP/PReP/PMac. -- Tom
