Sure:

/*
* PRM parameter buffer - normalized to system physical address, as described
* in the section "PRM Parameter Buffer" in the aforementioned spec.
*/
struct norm_to_spa_param_buf {
...
} __packed;

and you'll have to mention the spec in the prm.c file, at the top.

This way readers can immediately map it to the place in the spec.

Thx.
