Change 96498 by imp at imp_hammer on 2006/05/01 17:34:07

	For interrupt vector 6, use the format needed by the boot
	loader in the AT91RM9200 when booting off of DataFlash parts.
	
	# NOTE: This needs to be tweaked for each part that might have
	# on the SPI bus, as we have to encode page size and number of
	# pages into this vector...  On the other hand, we'll have this
	# data once the boot loader is in memory and can pass it to the
	# kernel in some manner...
