[PATCH 38/49] image: Drop IMAGE_ENABLE_EN/DECRYPT defines
Simon Glass
sjg at chromium.org
Tue May 4 01:11:25 CEST 2021
Add a host Kconfigs for IMAGE_ENABLE_ENCRYPT. With this we can use
CONFIG_IS_ENABLED() directly in the host build, so drop the unnecessary
indirections IMAGE_IMAGE_ENABLE_ENCRYPT and IMAGE_IMAGE_ENABLE_DECRYPT.
