No, it is the PALcode that's different. MILO does *not* contain the SRM
PALcode; it contains a modified version of the evaluation board PALcode
which is not the same at all. The MILO PAL may be more "SRM-like" in
that it implements the same CALL_PAL entry points and the same memory
management scheme, but it implements interrupts differently and it is
quite different internally.

That is one of the reasons why one of the config options is
"Use SRM as bootloader?"...
