Subject: [U-Boot] [PATCH v2 4/6] ARM: vf610: Enable caches
Date: Wed, 8 Apr 2015 18:50:08 +0530 [thread overview]
Message-ID: <8c0da8394309a2df54b1bc187751c38ef4205551.1428497492.git.maitysanchayan@gmail.com> (raw)
In-Reply-To: <cover.1428497492.git.maitysanchayan@gmail.com>
From: Stefan Agner <stefan@agner.ch>
Enables caches which provides a rather huge speedup of the boot loader.
Also mark the on-chip RAM as cachable since this is the area U-Boot runs
from.
