And when is that done and ready? pci_scan_bus()?
Lemme see if I understand the ordering correctly:
1. PCI needs to be initialized and all devices on the bus registered
2. AMD NB needs to run and enumerate the NBs so that the SMN access which you
need, can work.
3. acpi_scan_init()
4. i2c-designware-platdrv registration
Close?
Now, Mario, remind me again, pls, why can't they use the MSR to get the PSP MMIO
base. It has changed but why?
Maybe we should talk offlist first.
Thx.
