From ff143d55564373c2a5e8a128a71223f26ee2420f Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Tue, 10 Oct 2017 16:21:12 +0200 Subject: [PATCH] arm: mark save_boot_params_ret as a function As no '.type' was set for save_boot_params_ret in start.S, binutils did not track whether it was emitted as A32 or T32. By properly marking save_boot_params_ret as a potential function entry, we can make sure that the compiler will insert the appropriate instructions for branching to save_boot_params_ret both for call-sites emitted as A32 and T32.
