2020-09-09hw/riscv: Move sifive_gpio model to hw/gpioBin Meng1-7/+0
This is an effort to clean up the hw/riscv directory. Ideally it should only contain the RISC-V SoC / machine codes plus generic codes. Let's move sifive_gpio model to hw/gpio directory. Note this also removes the trace-events in the hw/riscv directory, since gpio is the only supported trace target in that directory.

2019-05-24SiFive RISC-V GPIO DeviceFabien Chouteau1-0/+7
QEMU model of the GPIO device on the SiFive E300 series SOCs. The pins are not used by a board definition yet, however this implementation can already be used to trigger GPIO interrupts from the software by configuring a pin as both output and input.
