Let's clean up behind ourselves and move the (newly defined) TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE into Kconfig. Given that 0x0 might be considered to be valid values for TPL_TEXT_BASE and TPL_STACK, we need to introduce helper config options ("TPL_NEEDS_SEPARATE_...") to indicate that these symbols are used (and not inherited from their SPL variants) for any given target-platform.
