mmmhhh... allocating in boot time as much as we want and then copy
what we need? It doesn't look that pretty to me.

Can you explain what's the use of the naming other than
debugging?

In that case, when the new chip will come, we would need to
figure out something, but for sure I don't see it as a good idea
to leave allocated unused structures.
