In most cases, the kernel will be loaded into 0x100000 during boot, so the kernel run-time address range from 0xc0100000 on. But it seems that your kernel compile-time address range from 0xc0f00000 on. Please check CONFIG_PHYSICAL_START in your .config. In most cases, it will be set to 0x100000, so that it is same as run-time address in most cases.
