From 56f6e31e7b7e06a66a0efd5464fa4257de7ec242 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 1 Sep 2020 09:38:59 +0800 Subject: hw/riscv: Initial support for Microchip PolarFire SoC Icicle Kit board This is an initial support for Microchip PolarFire SoC Icicle Kit. The Icicle Kit board integrates a PolarFire SoC, with one SiFive's E51 plus four U54 cores and many on-chip peripherals and an FPGA. For more details about Microchip PolarFire Soc, please see: https://www.microsemi.com/product-directory/soc-fpgas/5498-polarfire-soc-fpga Unlike SiFive FU540, the RISC-V core resect vector is at 0x20220000. The following perepherals are created as an unimplemented device: - Bus Error Uint 0/1/2/3/4 - L2 cache controller - SYSREG - MPUCFG - IOSCBCFG More devices will be added later. The BIOS image used by this machine is hss.bin, aka Hart Software Services, which can be built from: https://github.com/polarfire-soc/hart-software-services To launch this machine: $ qemu-system-riscv64 -nographic -M microchip-icicle-kit The memory is set to 1 GiB by default to match the hardware. A sanity check on ram size is performed in the machine init routine to prompt user to increase the RAM size to > 1 GiB when less than 1 GiB ram is detected.
