these lines explain a lot of how the mediatek exploit i was reviewing
a session or two on these phones worked:
CMD_READ16      0xa2    Read data from the SoC memory (16 bit length parameter)
CMD_WRITE16     0xd2    Write data into SoC memory (16 bit length parameter)
CMD_READ32      0xd1    Read data from the SoC memory (32 bit length parameter)
CMD_WRITE32     0xd4    Write data into SoC memory (32 bit length parameter)
it can read and write from SoC memory
the commenting in the exploit talked about this, but i didn't know the commands
