I don't see any references to "available" in the Linux code, except for some exotic machines. Neither does yaboot use anything like that. yaboot loads under qemu, but hangs trying to load the Linux kernel (both extracted from the Fedora 8 rescue disk), so I don't know if Linux would boot. It seems to me that Linux uses "#size-cells" and "#address-cells" (see drivers/of/base.c and arch/powerpc/kernel/prom_parse.c) As for yaboot, I have no idea. It gets a handle for "/memory" but never uses it. I don't see any references to "cells". > In any case, if you have to make this assumption, considering reusing the > HEAP_MIN_SIZE macro, which has the same meaning. OK, I'll try. -- Regards, Pavel Roskin _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
