21 * The nodes are matched with the physical SDRAM banks as follows:
23 * node 0: 0xa0000000-0xa3ffffff --> 0xc0000000-0xc3ffffff
24 * node 1: 0xa4000000-0xa7ffffff --> 0xc4000000-0xc7ffffff
25 * node 2: 0xa8000000-0xabffffff --> 0xc8000000-0xcbffffff
26 * node 3: 0xac000000-0xafffffff --> 0xcc000000-0xcfffffff
28 * This needs a node mem size of 26 bits.
