From 6bd2372094ab4827547ec0d3e5a258b72810cafd Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 2 Dec 2022 16:42:17 -0500 Subject: [PATCH] env: Rework ENV_IS_EMBEDDED and related logic slightly - Drop CONFIG_BUILD_ENVCRC as this is never set directly but instead means ENV_IS_EMBEDDED, so reference that in code and rename the Makefile usage to BUILD_ENVCRC. - Remove extra-$(CONFIG_ENV_IS_EMBEDDED) line as it could never be true, and likely why there is an extra- line for CONFIG_ENV_IS_IN_FLASH (the only use case today of embedded environments). - With these slight changes we can then see that using the calculated symbol of ENV_IS_EMBEDDED is the right thing to use in any code which needs to know this situation and can remove CONFIG_ENV_IS_EMBEDDED entirely.
