Subject: artik530: set the booting device in environemnt value
X-Git-Tag: submit/tizen/20180327.075642~55
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dc2e1a3bda9dbb0a33aec615a596910143eae0ee;p=profile%2Fcommon%2Fplatform%2Fkernel%2Fu-boot-artik7.git

artik530: set the booting device in environemnt value

set_booting_device shoud be set dynamically after checking OM pin.
eMMC boot - bootdev = mmcblk0 (rootdev = 0)
SD boot	  - bootdev = mmcblk1 (rootdev = 1)

The 'bootdev' env variable should be passed to kernel side after including
it in cmdline.
