// Configuration memory stores various hardware/kernel configuration settings. This memory page is
// read-only for ARM11 processes. I'm guessing this would normally be written to by the firmware/
// bootrom. Because we're not emulating this, and essentially just "stubbing" the functionality, I'm
// putting this as a subset of HLE for now.
