You mean 0x80h to 0xECh ?
MMIO base / limit
PCI IO base / limit
Config base / limit

That's my next target...

I have questions, though:

- I've got reserved values for Interleave Enable: Reserved 0b010, is
that normal, or a bug in my code ?

- In the doc, page 70 of 26094.pdf

3.4.4        DRAM Address Map
For the purposes of this comparison, the lower unspecified
bits of the base are assumed to be 0s and the lower unspecified bits
of the limit are assumed to be 1s.

For the limit registers I assumed the unspecified bits are 0-24, and I
set them to 0xFFFFFF.
Is that the right thing to do ?
Idem for base registers, with 24 bits set to 0x000000 ?
