 pins are
JTAG_MS0 JTAG_CK0 JTAG_DO0 JTAG_DIO JTAG_MS1 JTAG_DI1 JTAG_DO1
JTAG_CK1 and JTAG_SEL ok actually some of the JTAG pins can be
multi-function multiplexed.

so, interestingly, it looks like there are 2 JTAG ports!

 no idea what that lot's compatible with - it'd be crazy to have it
proprietary, it would cost allwinner time and money to write their own
tools.

 doesn't look like it.  no mention of JTAG other than the pin-pads and
a brief overview with description of each pin, in the datasheet.  it's
_that_ kind of datasheet :)  however, we know that information is
missing from it (it's more like "brief reminder notes") so there could
be something else.
