Subject: kernel-fit-image: make kernel entry point and load address optional
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=54c4b4826a3a67fbfef23c93356bfd7e5cb097c1;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

kernel-fit-image: make kernel entry point and load address optional

With image type kernel_noload, these are not used, and with [1] and
[2], U-Boot will not require them anymore for this image type. Allow
omitting them from image generation.
