Having said that I'm wondering if this should be in
arch/arm/mach-kirkwood/include/mach/config.h or automatically selected
via Kconfig. As far as I can tell prior to commit 93b283d49f93 ("ARM:
CPU: arm926ejs: Consolidate cache routines to common file") the
kirkwood boards didn't have and dcache support. It might be possible
to update the various drivers to use the proper DMA apis but for
2019.03 I think it might be safer just to run with
CONFIG_SYS_DCACHE_OFF.
