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 v2: * Add documentation update. * In patch 3, warn if no device tree is specified. * In patch 4, use riscv_find_firmware() to locate the firmware shipped with Qemu. v3: * In patch 4, add support for Qemu test runs.
