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.

hw/riscv: microchip_pfsoc: fix kernel panics due to missing peripherals Booting using "Direct Kernel Boot" for PolarFire SoC & skipping u-boot entirely is probably not advisable, but it does at least show signs of life. Recent Linux kernel versions make use of peripherals that are missing definitions in QEMU and lead to kernel panics. These issues almost certain rear their head for other methods of booting, but I was unable to figure out a suitable HSS version that is recent enough to support these peripherals & works with QEMU. With these peripherals added, booting a kernel with the following hangs hangs waiting for the system controller's hwrng, but the kernel no longer panics. With the Linux driver for hwrng disabled, it boots to console. qemu-system-riscv64 -M microchip-icicle-kit \ -m 2G -smp 5 \ -kernel $(vmlinux_bin) \ -dtb $(dtb)\ -initrd $(initramfs) \ -display none -serial null \ -serial stdio More peripherals are added than strictly required to fix the panics in the hopes of avoiding a replication of this problem in the future. Some of the peripherals which are in the device tree for recent kernels are implemented in the FPGA fabric. The eMMC/SD mux, which exists as an unimplemented device is replaced by a wider entry. This updated entry covers both the mux & the remainder of the FPGA fabric connected to the MSS using Fabric Interrconnect (FIC) 3.

hw/riscv: microchip_pfsoc: fix kernel panics due to missing peripherals Booting using "Direct Kernel Boot" for PolarFire SoC & skipping u-boot entirely is probably not advisable, but it does at least show signs of life. Recent Linux kernel versions make use of peripherals that are missing definitions in QEMU and lead to kernel panics. These issues almost certain rear their head for other methods of booting, but I was unable to figure out a suitable HSS version that is recent enough to support these peripherals & works with QEMU. With these peripherals added, booting a kernel with the following hangs hangs waiting for the system controller's hwrng, but the kernel no longer panics. With the Linux driver for hwrng disabled, it boots to console. qemu-system-riscv64 -M microchip-icicle-kit \ -m 2G -smp 5 \ -kernel $(vmlinux_bin) \ -dtb $(dtb)\ -initrd $(initramfs) \ -display none -serial null \ -serial stdio More peripherals are added than strictly required to fix the panics in the hopes of avoiding a replication of this problem in the future. Some of the peripherals which are in the device tree for recent kernels are implemented in the FPGA fabric. The eMMC/SD mux, which exists as an unimplemented device is replaced by a wider entry. This updated entry covers both the mux & the remainder of the FPGA fabric connected to the MSS using Fabric Interrconnect (FIC) 3.

hw/riscv: microchip_pfsoc: Correct DDR memory map When system memory is larger than 1 GiB (high memory), PolarFire SoC maps it at address 0x10_0000_0000. Address 0xC000_0000 and above is aliased to the same 1 GiB low memory with different cache attributes. At present QEMU maps the system memory contiguously from 0x8000_0000. This corrects the wrong QEMU logic. Note address 0x14_0000_0000 is the alias to the high memory, and even physical memory is only 1 GiB, the HSS codes still tries to probe the high memory alias address. It seems there is no issue on the real hardware, so we will have to take that into the consideration in our emulation. Due to this, we we increase the default system memory size to 1537 MiB (the minimum required high memory size by HSS) so that user gets notified an error when less than 1537 MiB is specified.

hw/{misc, riscv}: pfsoc: add system controller as unimplemented The system controller on PolarFire SoC is access via a mailbox. The control registers for this mailbox lie in the "IOSCB" region & the interrupt is cleared via write to the "SYSREG" region. It also has a QSPI controller, usually connected to a flash chip, that is used for storing FPGA bitstreams and used for In-Application Programming (IAP). Linux has an implementation of the system controller, through which the hwrng is accessed, leading to load/store access faults. Add the QSPI as unimplemented and a very basic (effectively unimplemented) version of the system controller's mailbox. Rather than purely marking the regions as unimplemented, service the mailbox requests by reporting failures and raising the interrupt so a guest can better handle the lack of support.
