1* Marvell Feroceon Cache

3Required properties:
4- compatible : Should be either "marvell,feroceon-cache" or
5 "marvell,kirkwood-cache".
6
7Optional properties:
8- reg : Address of the L2 cache control register. Mandatory for
9 "marvell,kirkwood-cache", not used by "marvell,feroceon-cache"
10

13 l2: l2-cache@20128 {
14 compatible = "marvell,kirkwood-cache";
15 reg = <0x20128 0x4>;
