Dumped from a Radxa Cubie A7A board.

It seems that on "unsecure" chips the HS-BROM part cannot be read (the result is all 0).

What are the base addresses for these ROMs?

EDIT: I'm assuming both are at 0 due to the vector table.

The user manual lists different address blocks for 3 different ROMs, FIXS-BROM is at 0x0, NS-BROM is at 0x17000 (the yet undumped HS-BROM is at 0x11000).
