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
