Egads... They aren't "tightly closed". Just there's no way to enumerate what devices are on what IO on the chip. - Don't get me wrong, many dealers just don't broadcast what's on a fabless-fab. Doesn't mean they're closed. Go hire someone who speaks and types Mandarin and get the info about "Gongkai". We were at this place once before, with 16 bit soundcards and ISA, for those of you that remember. In those days, we had to set IRQ and I/O so the device could communicate with the computer. And those devices had to correspond with each other. It was a hot mess, but what we had. MCA tried to fix it, with proprietary crappiness, but PCI actually won out. In reality, ARM is too open, and has too manhy ways in which hardware can be added. That causes problems, because there's no detection routines - "detection" can crash certain chips.
