	  For example, the bootable U-Boot format (created with

	  you write to flash might start at say 0x20080000, you have
	  to add 0x40 to get the kernel's CONFIG_ROM base as it will come
	  after the header.

comment "Speed Optimizations"
config CONFIG_BFIN_INS_LOWOVERHEAD
	bool "ins[bwl] low overhead, higher interrupt latency"
	default y
	depends on !CONFIG_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.
