Add an initial VPL build for sandbox. This includes the flow: TPL (with of-platdata) -> VPL -> SPL -> U-Boot To run it: ./tpl/u-boot-tpl -D The -D is needed to get the default device tree, which includes the serial console info. Add a Makefile check for OF_HOSTFILE which is the option that enables devicetree control on sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
