Actually, Broadcom does. ARM delivers the DMP plugin. This adds additional register space with each core and each core is identified with a vendor id (maintained by JEDEC to assure it is unique), a core id, and a core class. Another used interconnect is SSB which also offers discovery functionality. > Outside of the Primecell stuff, I'm unaware of anyone adding any kind > of discovery mechanism to SoC based devices. Not sure either. Gr. AvS -- "The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents." - "The Call of Cthulhu"
