Hi Thomas
What physical address does this come out to? All Orion platforms have
the serial port at the same place, 0xf1012000. If 370/XP is the same,
i suggest dropping this #include, hard code the address, and we share
the implementation for all SoCs.
If however, the ASIC engineers have decided to move it, we need some
extra logic to handle different base addresses for Dove and 370/XP
which should be supportable in one kernel binary.
Andrew
