65 * Row, column and bank mapping is derived after allowing for interleave
66 * from the normalized dram address through the tables of BKDG 3.29
67 * section 3.5.6.1. We have tables for:
68 *
69 * . rev CG and earlier, 64-bit MC mode
70 * . rev CG and earlier, 128-bit MC mode
71 * . rev D and later, 64-bit MC mode (no bank swizzling if rev E)
72 * . rev D and later, 128-bit MC mode (no bank swizzling if rev E)
73 * . rev E and later, 64-bit MC mode with bank swizzling
74 * . rev E and later, 128-bit MC mode with bank swizzling
75 *
76 * Each table is indexed by CS Mode (equivalently, CS size) and tells us
77 * which bits of the normalized dram address (i.e., the address modified for
78 * the local MC base address and with node interleave selection bits removed)
79 * to use in forming the column address, row address and internal bank
80 * selection.
81 *
82 * Note that for rev CG and earlier there is some overloading of CS mode
83 * encoding such that we do not know the number of row and column address
84 * bits from the CS mode alone, e.g., for 128MB DIMM modules we may have
85 * 13 row bits and 9 column, or 12 row and 10 column. In these case the
86 * tables held in the structures defined below will have a duplicated bit
87 * number in the row and column bits. In these ambiguous cases cm_rc_ambig
88 * should be set in the table.
