ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR has been enabled as default configs to Marvell PXA168/910/MMP2 platforms.
Introduction of PHYS_VIRT config as default would enable phy-to-virt and virt-to-phy translation function at boot and module loading time and enforce dynamic reallocation of memory. AUTO_ZRELADDR config would enable calculation of kernel load address at run time.
PHYS_VIRT config is mutually exclusive to XIP_KERNEL, XIP_KERNEL is used in systems with NOR flash devices, and ZRELADDR config is mutually exclusive to ZBOOT_ROM.
CFT::Call For Testing
Requesting maintainers of Marvell PXA168/910/MMP2 platforms to evaluate the changes on the board and comment, as I dont have the board for testing and also requesting an ACK
