There are two 64 MB outbound memory windows at bus addresses
0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI
memory. Currently, on iop32x, only the lower window is available for
allocations, limiting the available space to 64 MB. On iop33x the full
128 MB can be allocated, but the translation value is wrong for the
upper window.
The patch enables the full 128 MB space on iop32x and corrects the
initialization of OMWTVR1. Redundant definitions are deleted. Tested
using a Thecus N2100 board with a graphics adapter in the expansion
slot. Both windows are in use:

Innovation) Volari Z7 (prog-if 00 [VGA controller])
