2020-09-14hw/timer/armv7m_systick: assert that board code set system_clock_scalePeter Maydell
It is the responsibility of board code for an armv7m system to set system_clock_scale appropriately for the CPU speed of the core. If it forgets to do this, then QEMU will hang if the guest tries to use the systick timer in the "tick at the CPU clock frequency" mode. We forgot that in a couple of our boards (see commits ce4f70e81ed23c93f, e7e5a9595ab1136). Add an assertion in the systick reset method so we don't let any new boards in with the same bug.

2020-09-09hw/riscv: microchip_pfsoc: Connect 2 Cadence GEMsBin Meng
Microchip PolarFire SoC integrates 2 Candence GEMs to provide IEEE 802.3 standard-compliant 10/100/1000 Mbps ethernet interface. On the Icicle Kit board, GEM0 connects to a PHY at address 8 while GEM1 connects to a PHY at address 9. The 2nd stage bootloader (U-Boot) is using GEM1 by default, so we must specify 2 '-nic' options from the command line in order to get a working ethernet.

When cadence_gem model was created for Xilinx boards, the PHY address was hard-coded to 23 in the GEM model. Now that we have introduced a property we can use that to tell GEM model what our PHY address is. Change all boards' GEM 'phy-addr' property value to 23, and set the PHY address default value to 0 in the GEM model.

2020-09-09hw/riscv: microchip_pfsoc: Connect a Cadence SDHCI controller and an SD cardBin Meng
Microchip PolarFire SoC integrates one Cadence SDHCI controller. On the Icicle Kit board, one eMMC chip and an external SD card connect to this controller depending on different configuration. As QEMU does not support eMMC yet, we just emulate the SD card configuration. To test this, the Hart Software Services (HSS) should choose the SD card configuration: $ cp boards/icicle-kit-es/def_config.sdcard .config $ make BOARD=icicle-kit-es The SD card image can be built from the Yocto BSP at: https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp Note the generated SD card image should be resized before use: $ qemu-img resize /path/to/sdcard.img 4G Launch QEMU with the following command: $ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img Signed-off-by: Bin Meng <bin.meng@windriver.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-Id: <1598924352-89526-9-git-send-email-bmeng.cn@gmail.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>

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.
