Lorenzo Miori 60592165ca Samsung YP-R0 hosted target code refactoring
As per title this patch aims at splitting common target
code and specific target code in a better way to
support future ports within the same environment
(e.g. Samsung YP-R1 where the Linux and the SoC
are the same, with differences in hardware devices
handling)
