/* green-eye injected-service SDK header.
*
* A green-eye service is position-independent RV64 code loaded into the
* target's RAM by the debugger. Nothing in the firmware links against it,
* so it must not reference globals, absolute addresses or libc: every
* function it calls must be one it brings with it (or a function whose
* address the injector passes in).
*
* On the demo uproc, the injector stores the service entry in the control
* block's handler table and the firmware dispatches commands 16..23 to it.
* On a future GSP-RM simulator the same shape becomes an RM engine entry
* registered with the simulated RM core.
