Since ARCH_MULTIPLATFORM explicitly selects ARM_PATCH_PHYS_VIRT, even though ARCH_MULTIPLATFORM has 'depends on !XIP_KERNEL', ARM_PATCH_PHYS_VIRT is still forcibly selected. The result is that PHYS_OFFSET depends on !ARM_PATCH_PHYS_VIRT. This means you cannot enter a physical RAM address for an XIP kernel and you cannot build.
Given that it is already clear in the Kconfig that ARM_PATCH_PHYS_VIRT and XIP_KERNEL do not go well together (read the help for ARM_PATCH_PHYS_VIRT), adding this condition to ARCH_MULTIPLATFORM is logical and will fix this build issue.
