Subject: [PATCH v3 10/16] hw/riscv: microchip_pfsoc: Connect a DMA controller
Date: Tue, 1 Sep 2020 09:39:05 +0800 [thread overview]
Message-ID: <1598924352-89526-11-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1598924352-89526-1-git-send-email-bmeng.cn@gmail.com>
From: Bin Meng <bin.meng@windriver.com>
On the Icicle Kit board, the HSS firmware utilizes the on-chip DMA
controller to move the 2nd stage bootloader in the system memory.
Let's connect a DMA controller to Microchip PolarFire SoC.
Signed-off-by: Bin Meng <bin.meng@windriver.com>
