--- Comment #65 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
total fail on my part.  the resource_table_pads is a Pin/Resource
not a Signal or a Record: of course it can't be set/got.

fixed by instead registering the actual Signal/Record (named the "pin"
in Platform resource terminology, *not* the port which is the Pin/Resource)

i made it a dict-of-dicts so there is a dict by keynames
'gpio_0__gpio0__o' and then the pin named 'o', 'oe', or 'i'
inside that.

oe is its *own pin* and it should be accessed as:

    gpio0_oe = top.jtag.boundary_scan_pads['gpio_0__gpio0__oe']['o']

because it is actually an *output*.  long story.
