It's bad enough that DEBUG_LL works like that.
Yes it's doing the same thing as DEBUG_LL. DEBUG_LL hides things in a per-platform assembler file in addition to config. > Can't you put the relevant information into the device tree > so that it works on multiplatform kernels? That's the way > the kernel's chosen to store its "this is the config for > this platform" data, after all... I assumed if it could be done, DEBUG_LL would be doing it. It's starting time in assembler before the MMU is switched on. I don't think there's any existing code for walking the dtb at that time. Maybe it can start time a bit later after MMU and use the early dtb walking bits, I'll take a look but it's not a normal situation and may not have a normal solution. -Andy _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
