From b3ed6ce7808e8771fb1bca67b0276a8ad6bf1702 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 28 Jul 2017 20:02:34 +0200 Subject: [PATCH] spl: support TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE via Kconfig 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.
