Since the size of SPL can't be exceeded 0x8000 bytes in RK3288, it is not possible add new SPL features like Falcon mode or etc. So add TPL stage so-that adding new features to SPL is possible. - TPL: DRAM init, clocks - SPL: MMC, falcon, etc Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Acked-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
