Booting the microchip-icicle-kit machine using the latest PolarFire SoC Hart Software Services (HSS) no longer works since Qemu lacks support for several registers (clocks, DRAM controller). Also reading from the SDCard does not work currently.
In order to allow tests runs for real-time kernels such as RTEMS and Zephyr, improve the boot customization. This patch set enables a direct run of kernel executables, for example: qemu-system-riscv64 -no-reboot -nographic \ -serial null -serial mon:stdio \ -smp 2 \ -bios none \ -machine microchip-icicle-kit,clint-timebase-frequency=10000000 \ -kernel rtos.elf Sebastian Huber (5): hw/misc: Add MPFS system reset support hw/riscv: More flexible FDT placement for MPFS hw/riscv: Make FDT optional for MPFS hw/riscv: Allow direct start of kernel for MPFS hw/riscv: Configurable MPFS CLINT timebase freq hw/misc/mchp_pfsoc_sysreg.c | 7 ++ hw/riscv/microchip_pfsoc.c | 147 +++++++++++++++++++++-------- include/hw/riscv/microchip_pfsoc.h | 1 + 3 files changed, 115 insertions(+), 40 deletions(-) -- 2.43.0
