_GLOBAL(_set_L2CR)
	/* Usage:
	
		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(0xB3A04000)		-	enables my G3 upgrade card:
							-	L2E set to turn on the cache
							-	L2SIZ set to 1MB
							-	L2CLK set to 1:1
							-	L2RAM set to pipelined syncronous late-write
							-	L2I set to perform a global invalidation
							-	L2OH set to 0.5 nS
							-	L2DF set because this upgrade card requires it
	
		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.
