Subject: imx: spl: Remove ifdefs in spl_mmc_boot_mode()
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=5fc5bac67b90f507b2e93bbcd1ddeafc8eb32278;p=u-boot.git

imx: spl: Remove ifdefs in spl_mmc_boot_mode()

It is hard to read code which contains nested ifdef blocks.  Replace
them with normal if-blocks and the IS_ENABLED() macro.  This is not only
more readable but also helps as both arms are validated by the compiler
in all cases.
