- Starting with ARC700 4.9, Cache line length is configurable,
- This option specifies "N", with Line-len = 2 power N
- So line lengths of 32, 64, 128 are specified by 5,6,7, respectively
- Linux only supports same line lengths for I and D caches.
+ Enable IO coherency unit to debug problems with caches and
+ DMA peripherals.
+ NOTE: as of today linux will not work properly if this option
+ is enabled in u-boot!
