spdmem matching (Was: envstat drivers on SUN Ultra-45?)

Hi,

I have my U45 running and notice this as well:

> [     1.000000] spdmem0 at iic0 addr 0x57
> [     1.000000] spdmem0: FPM
> [     1.000000] spdmem0: 0 rows, 0 cols, 0 banks, 0ns tRAC, 0ns tCAC

However it's not on a memory card.  We match because spdmem_i2c.c has an
entry matching the compatible string:

  { .compat = "i2c-at34c02" },

as well as (later) name matches for "dimm-spd" and "dimm".  Looking at
the ofctl output that I have handy, it looks like all the memory modules
have  "dimm-spd" or "dimm".  So, can we remove this compatible entry?

Regards,

Julian
