PS1, Line 23: 	sa_set_pci_bar(soc_fixed_pci_resources, ARRAY_SIZE(soc_fixed_pci_resources));
> I also tried this, it's working after bootblock_systemagent_early_init function.

Ah, good catch, thanks. `bootblock_systemagent_early_init()` enables PCIEXBAR, which is needed to enable MCHBAR using `sa_set_pci_bar()`.
