From 2bbed3ff8c7fa0c0fa3fd28a9497bf7a99e3388b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 25 Sep 2021 19:43:23 -0600 Subject: image: Use Kconfig to enable FIT_RSASSA_PSS on host Add a host Kconfig for FIT_RSASSA_PSS. With this we can use CONFIG_IS_ENABLED(FIT_RSASSA_PSS) directly in the host build, so drop the forcing of this in the image.h header. Drop the #ifdef around padding_pss_verify() too since it is not needed. Use the compiler to check the config where possible, instead of the preprocessor.
