Conceptually this is good.  I have some issues around order of the
patches, and where the Kconfig entries end up.  Looking over the series
we introduce usage of some CONFIG symbols prior to declaring them in
Kconfig.  This is more of a hard no now as it will break bisecting when
the test for no new CONFIG symbols is tripped.  The other problem is
that I think the symbols you're adding in
board/freescale/ls1043ardb/Kconfig need to be in
arch/arm/cpu/armv8/Kconfig and then use default ... if ... to give the
right address for the layerscape boards.
