Thanks for the information.  I'd like to incorporate the changes to
support kernel "eXecute In Place" on the ROM.

To do that, it's good to define the meaning of vmlinux, the Kernel
Image.  I'd like to keep this image as the one after "loaded".
Specifically, don't change the LMA of vmlinux for ROM here.  It's
better to have another step getting ROM image from vmlinux, and
let the loader to load data section into RAM.

Why?  I'm thinking about the case where we compress the image of data
section on ROM, people may introduce such feature when ROM is small.

I'll try to do that with linker script.  Will send the patch to discuss
further.
