SATA interface for NanoPi Neo

[John Klos <john%ziaspace.com@localhost>]

Hi, all,

I think the toughest problem I've had with NetBSD on the NanoPi lately is 
figuring out which NanoPi is which :P

I just tested a Neo 2 with a 64 bit image accidentally paired with a 32 
bit userland, and everything worked wonderfully.

I'm now testing a Neo with Friendly's "1-bay NAS dock":

Of course this is expected to be a USB device, but I don't understand 
their talk of master and slave. Is this just another way of saying host 
and device?

If it's just a "slave" device, then it should Just Work (tm). However, 
it's not found by the kernel:

Also, I'm guessing that the RTC should just be an I2C device. Is there an 
easy way to scan I2C from userland, or do I need a kernel with options 
I2C_SCAN?

Thanks!
John
