FWIW, at the last OLS there was interest expressed by at least one ARM-based platform and I'm working on a set of patches to add the device tree for MIPS. It's going very slowly and is dependent on a patchset to add support for our platform, so it will take a while to make it available. The important point, though, is that device tree is the only thing approaching a standard on any non-x86-based platform for passing structured information from the bootloader to the kernel. The command line is just not sufficient for this. -- David VomLehn - - - - - Cisco - - - - - This e-mail and any attachments may contain information which is confidential, proprietary, privileged or otherwise protected by law.
