[Qemu-devel] [PATCH 0/6] [RFC] New SPARC machine: Leon3

[Fabien Chouteau <chouteau@adacore.com>]

Hi everyone,
I'm glad to submit my first patches to the Qemu-devel list.

This patch set introduces a new SPARC V8 machine: Leon3. It's an open-source
VHDL System-On-Chip, well known in space industry (more information on
http://www.gaisler.com).

Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

Modifications have been done to the SPARC cpu emulation code to handle
Leon3's specific behavior:
 - IRQ management
 - Cache control
 - Asr17 (implementation-dependent Ancillary State Registers)
 - Shutdown

Please feel free to comment.

Regards,

Fabien Chouteau (6):
  Emulation of GRLIB GPTimer as defined in GRLIB IP Core User's Manual.
  Emulation of GRLIB IRQMP as defined in GRLIB IP Core User's Manual.
  Emulation of GRLIB APB UART as defined in GRLIB IP Core User's
    Manual.
  Header file for the GRLIB components.
  Emulation of Leon3.
  SPARCV8 asr17 register support.
