From b8cd7f439aa95df9509550c722c4e21e6b218d34 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sun, 23 Jan 2022 00:31:06 +0000 Subject: [PATCH] armv8: remove no longer needed lowlevel_init.S When we added Allwinner SoC support to ARMv8, we needed to pull in an implementation of lowlevel_init() calling the C function s_init(), as sunxi required it as this time. The last few patches got rid of this bogus requirement, and as sunxi was still the only user, we can now remove this lowlevel_init.S from ARMv8 altogether.
