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) Change-Id: I67b4918c46403b184d3d8f42ab5aae7d01037fd0 Reviewed-on: http://gerrit.rockbox.org/409 Reviewed-by: Thomas Martitz <kugel@rockbox.org> Tested-by: Thomas Martitz <kugel@rockbox.org>
