Sphinx was rendering firmware layout as html table, but since
we want to add sizes relations switch to plain text graphics.

What about the RSA?
key == RSA key == RSA signature
I followed notation from our header definition which uses "key_size"
but maybe it was too brave. What about "RSA key" to have a match ?

* The firmware may or may not have modulus key and exponent data.
The header,
* uCode and RSA signature are must-have components that will be used
by driver.
