Subject: rockchip: mkimage: play nice with dumpimage
X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=24aae93f97381185fdba0935b48f1e5cb716ae54

rockchip: mkimage: play nice with dumpimage

Dumpimage (it invoked with "-T rkspi" or "-T rksd") would not work due
to check_params failing. These changes ensure that we can both be called
with an empty imagename.
