Subject: [PATCH v2 RESEND 1/4] arm64: dts: Reserve memory regions for hi6220
Date: Thu, 21 Jan 2016 18:53:47 +0800 [thread overview]
Message-ID: <1453373630-4693-2-git-send-email-leo.yan@linaro.org> (raw)
In-Reply-To: <1453373630-4693-1-git-send-email-leo.yan@linaro.org>
On Hi6220, below memory regions in DDR have specific purpose:
0x05e0,0000 - 0x05ef,ffff: For MCU firmware using at runtime;
0x06df,f000 - 0x06df,ffff: For mailbox message data;
0x0740,f000 - 0x0740,ffff: For MCU firmware's section;
0x3e00,0000 - 0x3fff,ffff: For OP-TEE.
This patch reserves these memory regions in DT.
Signed-off-by: Leo Yan <leo.yan@linaro.org>
