Subject: [PATCH 01/10] ARM: cache: restore cache functions from the PBL
Date: Sat, 19 Oct 2013 14:18:42 +0200 [thread overview]
Message-ID: <1382185130-28995-2-git-send-email-a.heider@gmail.com> (raw)
In-Reply-To: <1382185130-28995-1-git-send-email-a.heider@gmail.com>
When using CONFIG_MMU_EARLY combined with CONFIG_PBL_IMAGE, the barebox
setup reuses the MMU setup from the PBL, but doesn't setup the cache
functions.
Set these up to guarantee proper early cache handing before mmu_initcall().
