+ ppc4xx: Clean up 440 exceptions handling
+
+ - Introduced dedicated switches for building 440 and 405 images required
+ for 440-specific machine instructions like 'rfmci' etc.
+
+ - Exception vectors moved to the proper location (_start moved away from
+ the critical exception handler space, which it occupied)
+
+ - CriticalInput now serviced (with default handler)
+
+ - MachineCheck properly serviced (added a dedicated handler and return
+ subroutine)
+
+ - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
+ unhandled and those not relevant for 4xx were eliminated)
+
+ - Eliminated Linux leftovers, removed dead code

+ [PATCH] Run new sequoia boards with an EBC speed of 83MHz
+
+ Because the Sequoia board does not boot with an EBC faster than 66MHz,
+ the clock divider are changed after the initial boot process.
+
+ This allows for maximum clocking speeds to be achieved on newer boards.
+ Sequoia boards with 666.66 MHz processors require that the EBC divider
+ be set to 3 in order to start the initial boot process at a slower EBC
+ speed. After the initial boot process, the divider can be set back to 2,
+ which will cause the boards to run at 83.333MHz. This is backward
+ compatible with boards with 533.33 MHz processors, as these boards will
+ already be set with an EBC divider of 2.
