From: Rob Herring <redacted> I've finally gotten back to this after several months. This is the 2nd part of mach/io.h removals. This series removes io.h on platforms with PCI by creating a fixed virtual I/O mapping and a common __io() macro. As several platforms have 2 1MB I/O windows, I've changed the fixed mapping to 2MB (vs. 1MB in the prior posting) and allow platforms to control the size. This also allows using a single 1MB section mapping rather than 4KB pages.
Looks really good, feel free to add my Reviewed-by on patches 2-15, since I've done a line-by-line walkthrough and could not find anything besides the trivial comments I gave.
I've only tested versatilepb under qemu, so any testing is appreciated. iop3xx and mv78xx0 have some risk of breaking as the PCI bus addresses are moved to 0 from matching the cpu host bus addesss.
Did you try running any devices that actually use I/O space in qemu? I think there are plenty of devices that you could use for testing that. Arnd
