38 * Bamboo has one bank onboard sdram (plus DIMM)
39 *
40 * Fixed memory is composed of :
41 * MT46V16M16TG-75 from Micron (x 2), 256Mb, 16 M x16, DDR266,
42 * 13 row add bits, 10 column add bits (but 12 row used only).
43 * ECC device: MT46V16M8TG-75 from Micron (x 1), 128Mb, x8, DDR266,
44 * 12 row add bits, 10 column add bits.
45 * Prepare a subset (only the used ones) of SPD data
46 *
47 * Note : if the ECC is enabled (SDRAM_ECC_ENABLE) the size of
48 * the corresponding bank is divided by 2 due to number of Row addresses
49 * 12 in the ECC module
50 *
51 * Assumes: 64 MB, ECC, non-registered
52 * PLB @ 133 MHz
