Subject: distro_bootcmd: read DHCP boot script name from a variable
X-Git-Tag: v2015.04-rc1~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cc11b39288c402ca14ebf4e4cc15c7a72569034b;p=platform%2Fkernel%2Fu-boot.git

distro_bootcmd: read DHCP boot script name from a variable

Modify $bootcmd_dhcp to read the downloaded script filename from an
environment variable rather than hard-coding it. This allows the user
(or another script) to select a different script name if they want,
without editing the whole value of $bootcmd_dhcp.
