Subject: fdt: Drop remaining preprocessor macros in fdtdec_setup()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ba83d8593bde7aec6055ea5fe200b8db6f1b0810;p=u-boot.git

fdt: Drop remaining preprocessor macros in fdtdec_setup()

We only have two choices for obtaining the devicetree. Simplify the code
to make that clear.
