If the early boot methods of acpi are happy that we have valid ACPI tables and acpi=off has not been passed. Then do not unflatted devicetree effectively disabling further hardware probing from DT.
I assume there's alternate method of getting bootargs/kernel command line and other chosen node properties like initrd in UEFI/ACPI boot. Does EFI stub provide it ? If not then how do you plan to get them ?
These are all extracted much earlier in boot sequence than this in early_init_dt_scan_chosen()
Thanks for the info, I misunderstood "Get pointer to '/chosen' and '/aliases' nodes for use everywhere" comment in unflatten_device_tree. I assumed the chosen node gets scanned here. Sorry for the noise.
