Subject: [U-Boot] [u-boot PATCH v4 03/10] ti_armv7_keystone2: Define scratch space in SRAM
Date: Mon, 13 Mar 2017 15:04:26 +0200	[thread overview]
Message-ID: <1489410273-10159-4-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1489410273-10159-1-git-send-email-rogerq@ti.com>

From: Franklin S Cooper Jr <fcooper@ti.com>

Scratch space can be used for features such as board detection. Define
an area within SRAM that can be used for this purpose.
