Subject: kbuild: Allow for CONFIG_SYS_CONFIG_NAME to be unset
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=bcd8bce57c6d3ac7b52feb021cdf18bfc359104b;p=u-boot.git

kbuild: Allow for CONFIG_SYS_CONFIG_NAME to be unset

It is possible to have a platform which does not require a board.h file
to build, but today we need an empty one for our generated config.h file
to be valid. Allow for omitting this file if CONFIG_SYS_CONFIG_NAME is
not set.
