[PATCH v2 23/23] ARM: Kirkwood: Remove DT support

Andrew Lunn
2014-02-15T10:20:21Z

Now that all the device tree support is in mach-mvebu, remove it from
mach-kirkwood.

Regenerate kirkwood_defconfig, removing all DT support, and a couple
of other redundent options have been removed in the process.
