From 6cc1a2af46c448e7d822fa4976a8d6e10fc5273b Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Mon, 23 Apr 2018 07:59:44 +0200 Subject: [PATCH] riscv: Enable function sections The linker can remove sections that are never addressed, so it makes a lot of sense to declare every function as an individual section. This reduces the output U-Boot code size by ~30kb for me.
