I no longer remember the details. I do remember spending a lot of time trying to figure out how to do this. I know I didn't want to write my own scan routine; maybe that's what stopped me. As it happens, we also did most of the development on a broken phyp which simply did not even have this property, no matter what, and so that may have brain-damaged me. I went for the "most elegant" solution, where "most elegant" is defined as "fewest lines of code", "least effort", etc. Manish may need some hands-on help to extract this token during early boot. Hopefully, he'll let us know. --linas _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
