From c6e77bb61a557dcf6f7440497634a5dc7ada0b3f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 18 Oct 2021 15:30:39 +0100 Subject: ARM: 9143/1: add CONFIG_PHYS_OFFSET default values For platforms that are not yet converted to ARCH_MULTIPLATFORM, we can disable CONFIG_ARM_PATCH_PHYS_VIRT, which in turn requires setting a correct address here. As we actualy know what all the values are supposed to be based on the old mach/memory.h header file contents (from git history), we can just add them here. This also solves a problem in Kconfig where 'make randconfig' fails to continue if no number is selected for a 'hex' option. Users can still override the number at configuration time, e.g. when the memory visible to the kernel starts at a nonstandard address on some machine, but it should no longer be required now. I originally posted this back in 2016, but the problem still persists. The patch has gotten much simpler though, as almost all platforms rely on ARM_PATCH_PHYS_VIRT now.
