2019-12-10	riscv: add functions for reading the IPI status	Lukas Auer
	Add the function riscv_get_ipi() for reading the pending status of IPIs. The supported controllers are Andes' Platform Level Interrupt Controller (PLIC), the Supervisor Binary Interface (SBI), and SiFive's Core Local Interruptor (CLINT).

2019-04-08	riscv: implement IPI platform functions using SBI	Lukas Auer
	The supervisor binary interface (SBI) provides the necessary functions to implement the platform IPI functions riscv_send_ipi() and riscv_clear_ipi(). Use it to implement them. This adds support for inter-processor interrupts (IPIs) on RISC-V CPUs running in supervisor mode. Support for machine mode is already available for CPUs that include the SiFive CLINT.
