Change subject: nb/intel/i440bx: add resources during read_resources()
......................................................................

Patch Set 2:
> Patch Set 2:
>
> Here are the i440BX limits:
>
> Max 1GB RAM
> Max 4 DIMM slots
> 4 DIMM slots only supported using registered DIMMs
> Max 256MB per DIMM (and of the x8 type only; the kind that has 256MB with chips on one side only are not supported, although our ram init can use them partially.)
>
> So, without registered DIMMs, the most memory "i can haz" is 768MB, which is what I'm testing with.

Thanks, Keith, for the info. find_pci_tolm() is still wrong based on my understanding of the chipset in that the register will reflect the correct answer since DRB7 << 23 can maximally be 1GiB.
