Subject: esdhc/usdhc: Fix warning when CONFIG_SYS_FSL_ESDHC_USE_PIO is not set
X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=10dc77716f41979e03baf3b847b97dc7279ef30d

esdhc/usdhc: Fix warning when CONFIG_SYS_FSL_ESDHC_USE_PIO is not set

In 7168977 we made calls to check_and_invalidate_dcache_range()
conditional on !CONFIG_SYS_FSL_ESDHC_USE_PIO.  Only define this function
in this case as well.
