At present TPL uses the same options as SPL support. In a few cases the board config enables or disables the SPL options depending on whether CONFIG_TPL_BUILD is defined. With the move to Kconfig, options are determined for the whole build and (without a hack like an #undef in a header file) cannot be controlled in this way. Create new TPL options for these and update users. This will allow Kconfig conversion to proceed for these boards. Signed-off-by: Simon Glass <sjg@chromium.org>
