Over the past few days I've started to convert arch/mips to use DT. So far none of the platforms (except maybe PowerTV?) seems to have a firmware that is passing a DT nor is there any 2nd stage bootloader that could do so. So as the 2nd best thing I've been working on .dts files to be compiled into the images. I've put a git tree of my current working tree online. It's absolutely work in progress so expect to encounter bugs. http://git.linux-mips.org/?p=linux-dt.git;a=summary (Gitweb) git://git.linux-mips.org/linux-dt.git http://www.linux-mips.org/wiki/Device_Tree (brief documentation & links) An incomplete to do list: o Sort out interface for firmware to pass a DT to the kernel. Because we have so many different firmware implementations this one might get a slight bit interesting. o Interface to select one of several builtin DT images. I am thinking of extending the existing MIPS_MACHINE() / machtype mechanism to play nicely with DT. o Finish and test AR7, Cobalt, Jazz, Malta, MIPSsim and SNI ports. o Convert the remaining platforms; find if it's actually sensible to convert all platforms. o I'm considering to make DT support a requirement for future MIPS platforms so you might as well start beating your firmware monkeys / ask Santa to put you a shiny new bootloader blob into the boot now. o Write more of the required infrastructure. o Write documentation Contributions and comments welcome, Ralf
