From cfbabb9ec6ba4979411ff8050638ac2628806beb Mon Sep 17 00:00:00 2001 From: Dongdong Zhang Date: Tue, 29 Nov 2022 11:54:07 +0800 Subject: [PATCH] firmware: Minor optimization for relocate The t3 register stores the address of _load_end. If relocation is not required, it is unnecessary to calculate the address of _load_end. This can reduce the operation time of two instructions.
