Subject: [PATCH 06/18] hw/riscv: microchip_pfsoc: Connect 5 MMUARTs
Date: Sat, 15 Aug 2020 00:40:44 +0800 [thread overview]
Message-ID: <1597423256-14847-7-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1597423256-14847-1-git-send-email-bmeng.cn@gmail.com>
From: Bin Meng <bin.meng@windriver.com>
Microchip PolarFire SoC has 5 MMUARTs, and the Icicle Kit board
wires 4 of them out. Let's connect all 5 MMUARTs.
