[U-Boot] [RFC/PATCH 1/1] sunxi: Populate the default environment for sunxi-based systems

[Karsten Merker <merker@debian.org>]

Predefine a set of standard environment variables (kernel_addr_r,
ramdisk_addr_r, fdt_addr_r and scriptaddr) to sensible values on
sunxi-based systems and provide a default environment that allows
autobooting of existing boot scripts which were written for
pre-mainlining u-boot-sunxi versions.
