Ultrascale+ GPIO internal pull-up/pull-down resistor values

Can anyone point me to documentation of the Ultrascale+ GPIO/MIO pull-up/pull-down resistor values?

Vivado allows you to select drive strength (2, 4, 8, 12 mA), but I cannot find a table of associated resistor values. Since you can assign different voltages to a bank, I assume such a table exists, but perhaps I am wrong.

Just remember they are not real resistors, but current source / sinks.
