Subject: bootstd: Move common zimage functions to bootm.h
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1a0810924a29311a330d717a2813d212865a5df0;p=u-boot.git

bootstd: Move common zimage functions to bootm.h

We want to avoid using #ifdefs around header files and in the code. It
makes sense to collect the various functions used for loading images into
a single header which can be included by all architectures. The best place
for this is the arch-neutral bootm.h header, so use that.

Move some zimage functions into this bootm.h header.
