Subject: [PATCH] Revert "tools: kwbimage: Do not hide usage of secure header
under CONFIG_ARMADA_38X"
This reverts commit b4f3cc2c42d97967a3a3c8796c340f6b07ecccac.
Addendum 2022-12-08, Ricardo Wurmus: This patch has been updated to introduce
CONFIG_FIT_PRELOAD to remove fit_pre_load_data, which depends on openssl.
