Subject: [PATCH v6 15/33] iommu/mediatek: Update oas for v7s
Date: Mon, 11 Jan 2021 19:18:56 +0800 [thread overview]
Message-ID: <20210111111914.22211-16-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210111111914.22211-1-yong.wu@mediatek.com>
This patch only updates oas in different SoCs.
If the SoC supports 4GB-mode and current dram size is 4GB, the oas is 33.
otherwise, it's still 32. In the lastest SoC, the oas is 35bits.
