From 1b3d24b7351b0a19cfcfe17bc2f5d654c5a2ebcd Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Tue, 26 Nov 2019 12:19:27 +0100 Subject: [PATCH] armv7m: cache: add invalidate_icache_all() stub This commit: https://gitlab.denx.de/u-boot/u-boot/commit/d409c962169bd293e39386d0ddfa64d5222a3be4 causes build failure with ICACHE enabled. This is due to missing invalidate_icache_all() stub. Let's add empty invalidate_icache_all() in the case where ICACHE is not enabled.
