Merged of mcp750 and mvme2307 BSP by Eric Valette <valette@crf.canon.fr>.

As part of this effort, the mpc750 libcpu code is now shared with the
ppc6xx.

+	 * When setting the L2CR register, you must do a few special things.  
+	 * If you are enabling the cache, you must perform a global invalidate. 
+	 * If you are disabling the cache, you must flush the cache contents first.
+	 * This routine takes care of doing these things.  When first
+	 * enabling the cache, make sure you pass in the L2CR you want, as well as 
+	 * passing in the global invalidate bit set.  A global invalidate will 
+	 * only be performed if the L2I bit is set in applyThis.  When enabling 
+	 * the cache, you should also set the L2E bit in applyThis.  If you
+	 * want to modify the L2CR contents after the cache has been enabled, 
+	 * the recommended procedure is to first call __setL2CR(0) to disable 
+	 * the cache and then call it again with the new values for L2CR.  Examples:
+	 *
+	 *	_setL2CR(0)		-	disables the cache
+	 *	_setL2CR(0xb9A14000)	-	enables my G3 MCP750 card:
+	 *				-	L2E set to turn on the cache
+	 *				-	L2SIZ set to 1MB
+	 *				-	L2CLK set to %2
+	 *				-	L2RAM set to pipelined syncronous late-write
+	 *				-	L2I set to perform a global invalidation
+	 *				-	L2OH set to 1 nS
+	 *
+	 * A similar call should work for your card.  You need to know the correct 
+	 * setting for your card and then place them in the fields I have outlined 
+	 * above.  Other fields support optional features, such as L2DO which caches 
+	 * only data, or L2TS which causes cache pushes from the L1 cache to go to 
+	 *the L2 cache instead of to main memory.
