[U-Boot] [PATCH v4 05/20] rockchip: Move bootrom helper compilation to a hidden option

[Heiko Stuebner]

Right now the ROCKCHIP_SPL_BACK_TO_BROM option both triggers
compilation of the bootrom hook-code as well as enabling the
behaviour of loading the full U-Boot via the boot.

New added socs may always need the bootrom code, while still
being able to decide between loading U-Boot regularly or via
the bootrom separately.

So move the compilation of the bootrom code to a hidden option
that gets selected by ROCKCHIP_SPL_BACK_TO_BROM, but can also
be selected by other parts.
