| * Bamboo has one bank onboard sdram (plus DIMM) |

| * Fixed memory is composed of : |
| * MT46V16M16TG-75 from Micron (x 2), 256Mb, 16 M x16, DDR266, |
| * 13 row add bits, 10 column add bits (but 12 row used only). |
| * ECC device: MT46V16M8TG-75 from Micron (x 1), 128Mb, x8, DDR266, |
| * 12 row add bits, 10 column add bits. |
| * Prepare a subset (only the used ones) of SPD data |
| * |
| * Note : if the ECC is enabled (SDRAM_ECC_ENABLE) the size of |
| * the corresponding bank is divided by 2 due to number of Row addresses |
| * 12 in the ECC module |
| * |
| * Assumes: 64 MB, ECC, non-registered |
