Subject: [PATCH 0/1] Fix Dreamcast GAPS PCI bridge

Hi all,

this patch fixes the G2-to-PCI bridge found in the SEGA Dreamcast
hardware, by setting the appropriate IOPORT base offset.

While being just a simple change, it's notable to mention that, when
combined with the DMAC fixes from e82e47584847, it allows Linux to boot
on the SEGA Dreamcast again, probably for the first time in a long
while.
