Comment (by Jeffrey Hill):
One is fairly quickly convinced that there will be an issue when "end <=
start" if we look at this line in the source. Refer to the PCI Bridge
specification to fully understand this part of the code. The bridge window
size registers at offset 0x20 and 0x24 are being programmed.
line 741:
{{{
tmp = ((res->end-1) & 0xfff00000) | (res->start >> 16);
}}}
