[PATCH v2 00/10] Instantiate VT82xx functions in host device
Posted by Bernhard Beschow 3 years, 5 months ago
v2:
* Keep the call to pci_ide_create_devs() in board code for consistency (Zoltan)
* Create rtc-time alias in board rather than in south bridge code
* Remove stale comments about PCI functions

v1:
This series instantiates all PCI functions of the VT82xx south bridges in the south bridges themselves.
For the IDE function this is especially important since its interrupt routing is configured in the
ISA function, hence doesn't make sense to instantiate it as a "Frankenstein" device. The interrupt
routing is currently hardcoded and changing that is currently not in the scope of this series.

Testing done:
* `qemu-system-ppc -machine pegasos2 -rtc base=localtime -device ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso -kernel morphos-3.17/boot.img`
  Boots successfully and it is possible to open games and tools.

* I was unable to test the fuloong2e board even before this series since it seems to be unfinished [1].
  A buildroot-baked kernel [2] booted but doesn't find its root partition, though the issues could be in the buildroot receipt I created.
