Due to increasing kernel image sizes we get problems when decompressing the kernel image. To fix this we need to change the addresses where we load and where we extract the kernel. Also we need to adapt the address where to load the CRAMFS image and where to load the DTB file. While at it also harmonize all boards for PPC and ARM to have the same values. Also we add a new variable "env_version", so that the userspace is able to detect if this is a u-boot binary with updated values or not.
