- * The implementation of this opcode in general consists of several

- * really old chipsets, the memory type reported by the strap bits
- * (0x101000) is assumed to be accurate on nv05 and newer.
- *
- * 2) Determination of the memory bus width. Usually done by a cunning
- * combination of writes to offsets 0x1c and 0x3c in the fb, and
- * seeing whether the written values are read back correctly.
- *
- * Only necessary on nv0x-nv1x and nv34, on the other cards we can
- * trust the straps.
- *
- * 3) Determination of how many of the card's RAM pads have ICs
- * attached, usually done by a cunning combination of writes to an
- * offset slightly less than the maximum memory reported by
- * NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
- *
- * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
- * logs of the VBIOS and kmmio traces of the binary driver POSTing the
- * card show nothing being done for this opcode. Why is it still listed
