Hi everyone, New version of the Leon3 emulation. Many modifications since v1, mostly to follow the Qemu architecture and to implement features in a more generic way.
Again, please feel free to comment. Regards, -------------------------------------------------------------------------------- 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 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.
