Commit 65939301acdb (arm: set initrd_start/initrd_end for fdt scan) caused the FDT initrd_start and initrd_end to override the phys_initrd_start and phys_initrd_size set by the initrd= kernel parameter. With this patch initrd_start and initrd_end will be overridden if phys_initrd_start and phys_initrd_size are set by the kernel initrd= parameter.
