From: Christopher Spinrath christopher.spinrath@rwth-aachen.de

In preparation for supporting the distro boot command, introduce the standard variables for specifying load addresses, which are documented in README and doc/README.distro, and replace the custom variables used so far with them.

Since the current address layout disregards an address for an initramfs, also switch to the load addresses used and proven by other imx6 boards (e.g. the wandboard and nitrogen6x), instead of going on with our own way.
