I am seeing below crash while trying to mount root file system.

I did git bisect and figure out commit "56adbb38727320375b2f695bd04600d766d8a1b3" i.e. "image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro" causing this crash. If I revert this patch, every things work perfectly.
Any suggestion.. Am I missing something!!
No, just my fault here, sorry, pushing a fix shortly.
