From 111a6af97acd9bca2ffe0b976c8962cfe8a9acc6 Mon Sep 17 00:00:00 2001 From: Phil Edworthy Date: Thu, 1 Jun 2017 07:33:28 +0100 Subject: [PATCH] arm: Add Kconfig symbols used for Linux asm compatibility Rather than change asm files that come from Linux, add the symbols to Kconfig. Since one of the symbols is for thumb2 builds, make CPU_V7M always select them.
