Subject: kbuild: add misc targets, help, ubootrelease, ubootversion
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ed1ca528aae1f3ae7400c5816e6d2cdb082ee785;p=u-boot.git

kbuild: add misc targets, help, ubootrelease, ubootversion

"help" target has been copied from Linux 3.13 and adjusted
for U-Boot.
Unlike Linux, cleaning is done on 4 levels:
clean, clobber, mrproper, distclean.
