To be clear, as I understand it, this mechanism is a hand off from the boot firmware to Linux. The boot firmware talks i2c to the device, does some stuff, writes it to memory and then linux reads that stuff. I agree it seems crazy to include a random physical address like that. The linux,sml-* names appear to have been used by IBM for a long time on their enterprise PPC platforms (see drivers/char/tpm/tpm_of.c), so I've expected we have to keep them? I asked Nayna to document this stuff IBM is doing so the rest of us in TPM land can have a hope of maintaining it...
