From bd47cdb78997f83bd170c389ef59de9eec65976a Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 29 Aug 2021 07:42:46 -0700 Subject: xtensa: move section symbols to asm/sections.h Introduce asm/sections.h and move section declarations to this header from setup.c. Assign section symbols char array type uniformly and drop address operator from section symbol references in code. Sort headers in setup.c while at it.
