I was thinking of writing a bootwrapper that would convert residual data to flat device tree. There is a lot of valuable information in the residual data, like the interrupt routing (which is correct if you can read the spec, which is not what the code in arch/ppc did).We were wondering the other day how reliable the residual data are...On the boards I use, they are very good. And there is some information (memory size, tb and cpu freq, etc...) that I'd rather take from the residual data than trying to guess.quoted
David Gibson's been toying with that too already, you should sync with him.I've not yet started to write anything (finishing a hardware project).
Ok, well, anyway, that's good to know that they are good. Ben.
