Subject: powerpc/boot: Only build board support files when required.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b81f18e55e9f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/boot: Only build board support files when required.

Currently we build all board files regardless of the final zImage
target.  This is sub-optimal (in terms on compilation) and leads to
problems in one platform needlessly causing failures for other
platforms.

Use the Kconfig variables to selectively construct this board files to
build.
