I did a quick hack: 20 files changed, 40 insertions(+), 3051 deletions(-) All the leon stuff is kept and there is room for more cleaning up. The kernel can build a sparc32_defconfig with the Gaisler toochain. This was a one hour quick hack that I cannot commit - it needs to be split up to allow some resemble of review. And it touched only arch/sparc/ - no sparc32 specific drivers were dropped. If we decide to chase this and we can drop sun4m/sun4d then maintaining leon will be simpler as a nice side effect. Sam
