From b2473a359763e27567993e7d8f37de82f57a0829 Mon Sep 17 00:00:00 2001 From: Usama Arif Date: Wed, 23 Oct 2024 18:14:26 +0100 Subject: of/fdt: add dt_phys arg to early_init_dt_scan and early_init_dt_verify __pa() is only intended to be used for linear map addresses and using it for initial_boot_params which is in fixmap for arm64 will give an incorrect value. Hence save the physical address when it is known at boot time when calling early_init_dt_scan for arm64 and use it at kexec time instead of converting the virtual address using __pa(). Note that arm64 doesn't need the FDT region reserved in the DT as the kernel explicitly reserves the passed in FDT. Therefore, only a debug warning is fixed with this change.
