In arm.py we currently use r9, as modern U-Boot versions do. This was not always the case, so we need some means to switch between r8/r9 based upon version info, inference, or user override.

Example can be found in 2012.10 version I've seen in the wild, from:
http://arago-project.org/git/meta-arago.git?p=meta-arago.git;a=blob;f=meta-arago-distro/recipes-bsp/u-boot/u-boot_2012.10-psp05.06.00.00.bb;h=fa2183e5bd3639252ef337777d504161a0f6251b;hb=093a05bb850c8d6a1922acf996f57fce20a6cd0d
