From c6ac6c1bd42b8948825697c88ba4ea00d61c5e2e Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Thu, 29 Jun 2017 01:38:49 +0200 Subject: [PATCH] spl: dm: Kconfig: split REGMAP/SYSCON support for TPL from SPL This change introduces TPL variants of the REGMAP and SYSCON config options (i.e. TPL_REGMAP and TPL_SYSCON in analogy to SPL_REGMAP and SPL_SYSCON) in preparation of a finer-grained feature selection for building feature-rich TPL variants.
