Subject: tizen: rpi: move bootscripts to tizen specific directory
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=02ef6b88b70ebfa54efa42ed03fcdd7e26dec415;p=platform%2Fkernel%2Fu-boot.git

tizen: rpi: move bootscripts to tizen specific directory

Move bootscripts from board/raspberrypi/rpi to tizen/bootscript/.
And combine to one script, because those are duplicated almost codes.
