From 6af4ab570db3dc71e877271a17e5e2b337e0bdc0 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 29 Sep 2019 19:55:09 -0700 Subject: xtensa: move MPU constants from .data to .ref.rodata MPU attribute mapping table is R/O, move it from .data to __REFCONST (as the rest of the _startup code where initialize_cacheattr is used is in the __REF section). This allows executing initialize_cacheattr before the data section of the XIP kernel is relocated to its place.
