From ce908a2f6f6d6e1d8ede485ee3f9f7d36ee3533c Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 1 Sep 2020 09:39:09 +0800 Subject: hw/riscv: microchip_pfsoc: Hook GPIO controllers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Microchip PolarFire SoC integrates 3 GPIOs controllers. It seems enough to create unimplemented devices to cover their register spaces at this point. With this commit, QEMU can boot to U-Boot (2nd stage bootloader) all the way to the Linux shell login prompt, with a modified HSS (1st stage bootloader).
