select ARM_PATCH_PHYS_VIRT as with ARM_PATCH_PHYS_VIRT you can patch boot_params at runtime or any recent bootloader will provide a valid atags pointer in r2 as point out by Russell on AT91 we never use XIP so se do not need PLAT_PHYS_OFFSET Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Patrice Vilchez <patrice.vilchez@atmel.com> Cc: Andrew Victor <linux@maxim.org.za> Cc: Russell King <rmk+kernel@arm.linux.org.uk>
