Subject: [PATCH v2 9/9] ARM: dts: keystone-k2g: Reserve MSM RAM for boot monitor
Date: Fri, 6 Jan 2017 15:57:33 -0600 [thread overview]
Message-ID: <20170106215733.41637-10-s-anna@ti.com> (raw)
In-Reply-To: <20170106215733.41637-1-s-anna@ti.com>
The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c0f7000
on 66AK2G SoCs, so add a reserved child node for the same.
This address is aligned to the values used within the latest boot
monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load
address to end of MSMC").
