SPARC: Added support for LEON3 TSIM/GRSIM simulator.
PATCH 10/13 SPARC: Added support for LEON3 TSIM/GRSIM simulator.
Hello Wolfgang,
This patch adds support for the LEON3 simulators TSIM and GRSIM.
The simulators GRSIM and TSIM for LEON3 has been added as a board. A separate board is needed due to that the FLASH CFI interface has not been implemented in the simulators. Configuring the GR-XC3S-1500 board without FLASH support should run in the simulator.
This patch is also available at
ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.
Best Regards,
Daniel Hellstrom
