In linux kernel since version 3.1 (release Date: 2011-10-24)
There are multiple Latency Units corresponding to the many
interfaces of the system bus arbiter (both CPU side as well as
the peripheral side).
To add latency to ALL memory transaction, choose Unit 0, otherwise
for finer grainer - interface wise latency, specify a bitmap (1 bit
per unit) of all units. e.g. 1,2,12 will be 0x1003
Unit 0 - System Arb and Mem Controller
Unit 1 - I$ and System Bus
Unit 2 - D$ and System Bus
..
