	  Make sure your ROM base does not include any file-header
	  information that is prepended to the kernel.

	  For example, the bootable U-Boot format (created with
	  mkimage) has a 64 byte header (0x40).  So while the image
	  you write to flash might start at say 0x20080000, you have
	  to add 0x40 to get the kernel's ROM base as it will come
	  after the header.

comment "Speed Optimizations"
config BFIN_INS_LOWOVERHEAD
	bool "ins[bwl] low overhead, higher interrupt latency"
	default y
	depends on !SMP
	help
	  Reads on the Blackfin are speculative. In Blackfin terms, this means
	  they can be interrupted at any time (even after they have been issued
	  on to the external bus), and re-issued after the interrupt occurs.
	  For memory - this is not a big deal, since memory does not change if
	  it sees a read.

	  If a FIFO is sitting on the end of the read, it will see two reads,
	  when the core only sees one since the FIFO receives both the read
	  which is cancelled (and not delivered to the core) and the one which
	  is re-issued (which is delivered to the core).

	  To solve this, interrupts are turned off before reads occur to
	  I/O space. This option controls which the overhead/latency of
	  controlling interrupts during this time
	   "n" turns interrupts off every read
		(higher overhead, but lower interrupt latency)
	   "y" turns interrupts off every loop
		(low overhead, but longer interrupt latency)

	  default behavior is to leave this set to on (type "Y"). If you are experiencing
	  interrupt latency issues, it is safe and OK to turn this off.
