Hi Tomasz,
I'm just checking to make sure we aren't deadlocked here, with me waiting
for you and you waiting for me. I gave you some comments about
abbreviations (MCFG/MMCFG/MMCONFIG/ECAM), weak functions, code placement
(drivers/acpi vs. drivers/pci), and the mmio_config_*() naming, so I've
been waiting to continue those discussions. But maybe you're waiting for
me, too?
I think this sort of cleanup is a great idea and I hope we can make some
progress on it. If it's easier to do it in small pieces, e.g., starting
out by moving code and renaming things with no functional changes, that
would be great with me.
