address 0xc0000000 and up (to the extend of RAM) in the kernel are
*virtual* addresses.  The kernel is setup up such that *virtual* address
0xc0000000 maps (via the MMU and its TLBs) to the first *physical*
address in RAM.

You might want to try loading/running rootfs/boot/zImage instead of
vmlinux. zImage is position-independant, that is it can be loaded
anywhere in RAM and on entry, figures out where it is, relocates
itself(if necessary) and decompresses the kernel into its intended
location and starts it.
