Very interesting, thanks for sharing this bit of history. Are you aware of other ARM systems using open firmware that we still support in Linux (besides the XO-1.75)? > Is there ever a point when old architectures leave the Linux tree, or > will people have to see grep hits from them until the end of time? As long as someone is interested in keeping an architecture or driver alive, it stays. If something is causing problems and we have reason to assume it will never be used again with current kernels, we toss them out. Russell has recently removed support for ARMv3 CPUs, but some of the StrongARM targets (especially SA-1100) are still being actively used, so the CPU support is not going away any time soon. If you have a bunch of Shark machines for testing and would like to port it over to device tree passing from its open firmware, you are definitely welcome ;-) Arnd -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
