I've seen the System on Chip of Raspberry Pi referred to usually as "BCM2835" (e.g. on Wikipedia), but sometimes as "BCM2708" (e.g. sources for Linux SPI driver are in bcm2708.c, or in comments to my other question).
Which is right, or are both - why? Specially, if there are inconsistencies in datasheets for both, which shall be understood as "more important"?
