From 603d15a572d5b1e2894db87b86d85a092dacdfd1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 25 Sep 2021 19:43:17 -0600 Subject: [PATCH] spl: cypto: Bring back SPL_ versions of SHA Unfortunately these were removed by mistake. This means that adding hash support to SPL brings in all software algorithms, with a substantial increase in code size. The origin of the problem was renaming them to SPL_FIT_xxx and then these were removed altogether in a later commit. Add them back. This aligns with CONFIG_MD5, for example, which has an SPL variant.
