The load address is where your uncompressed kernel gets loaded
(copied) to, and the entry point address is, umm, well, it's the
kernel's entry point address.

No, you cannot chose these addresses arbitrarily. They must match
your architecture, your board's memory map and your kernel
BTW: allthis has been discussed many times before on this list; it
would have been a good idea to search a bit in the archives.

ARM has usually ROM at address 0; you will not be able to copy your
kernel to this address; the following jump to this address provokes
