The second reg resource depends on where your firmware set up the SMC pram
regs. With U-boot, it's usually zero.
Note that as of 2.6.26-rc1, this is set up dynamically instead, and the
second resource should be 0x87fc 2.

It's the device-specific portion of the value that gets written to the CPM
command register (page, sub-block, and mcc channel).
