This patch enables ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR as default configs to versatile platform.
Introduction of PHYS_VIRT config as default enables phy-to-virt and virt-to-phy translation functions at boot and module loading time, and enforce dynamic reallocation of memory. PHYS_VIRT config is mutually exclusive to XIP_KERNEL, XIP_KERNEL is used in systems with NOR flash devices.
AUTO_ZRELADDR config enables auto calculation of the decompressed kernel image address. AUTO_ZRELADDR config is mutually exclusive to ZBOOT_ROM, and also assumes zImage to be loaded in the first 128MiB from start of memory.
CFT::Call For Testing
Requesting maintainers of Versatile platform to evaluate the changes on the board and comment, as I dont have the board for testing and also requesting an ACK.
