Problem Title:
LogiCORE PCI: Does it support Big or Little Endians?
Problem Description:
Urgency: Standard
General Description:
What kind of address ordering does the LogiCORE PCI interface use? The core
may be used with both Intel and Motorola machines which use Little-Endian
(lower addresses contain the LSBs) and Big-Endian (upper addresses contain
LSBs) schemes of byte ordering.
Solution 1:
The configuration space supports little-endian ordering as required by the
PCI specification, section 6.1: "All multi-byte numeric fields follow
little-endian ordering; that is, lower addresses contain the least significant
parts of the field."
