Because relocation is supported in recent Linux kernel, it is possible
that the run-time address is different with compile-time address. 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.
Best Regards,
Huang Ying
