From: Tom Rini Date: Mon, 15 May 2017 16:17:48 +0000 (-0400) Subject: FIT: Rename FIT_DISABLE_SHA256 to FIT_ENABLE_SHA256_SUPPORT X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0db7f6859fef41c1e95bcef75761054a01782d1b;p=u-boot.git FIT: Rename FIT_DISABLE_SHA256 to FIT_ENABLE_SHA256_SUPPORT We rename CONFIG_FIT_DISABLE_SHA256 to CONFIG_FIT_ENABLE_SHA256_SUPPORT which is enabled by default and now a positive option. Convert the handful of boards that were disabling it before to save space.
