This series allows leon3 emulations to record up 4 CPUs.
It requires some enhancements in the grlib_irqmp device and adding the
cpu_index field in the asr17 instruction.
It has been tested locally with various bareboard runtimes.
Clément Chigot (8):
sparc/grlib: split out the headers for each peripherals
intc/grlib_irqmp: add ncpus property
intc/grlib_irqmp: implements the multiprocessor status register
intc/grlib_irqmp: implements multicore irq
target/sparc: implement asr17 feature for smp
leon3: implement multiprocessor
leon3: check cpu_id in the tiny bootloader
MAINTAINERS: replace Fabien by myself as Leon3 maintainer
