[U-Boot] [U-Boot, v4, 24/66] rockchip: Makefile: allow selective inclusion of sdram_common.o from TPL/SPL/U-Boot

[Philipp Tomsich]

> The utility functions in sdram_common.c will be useful both for some
> SPL implementations (and if unused, the linked will discard these
> anyway) and for the full U-Boot stage.
> 
> This changes selects sdram_common.o through the $(SPL_TPL_) macro to
> allow better control of its inclusion through the CONFIG_ROM,
> CONFIG_SPL_RAM or CONFIG_TPL_RAM options.
