Subject: tegra: image: make bootscript standalone
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bbd665f38d6b48e56bb5ef38ee0eeceb02a8e129;p=openwrt%2Fstaging%2Fblocktrron.git

tegra: image: make bootscript standalone

Don't hard-code the PTUUID, use U-Boot commands to determine it, as some
partitioning tools could rewrite PTUUID when modifying partitions.
