From 1001502545ff0125c39232cf0e7f26d9213ab55f Mon Sep 17 00:00:00 2001 From: Trevor Woerner Date: Fri, 3 May 2019 09:41:00 -0400 Subject: CONFIG_SPL_SYS_[DI]CACHE_OFF: add While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances where these configuration items are conditional on SPL. This commit adds SPL variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates the configurations as required.
