| 15 | <h4>SYNOPSIS</h4> | |
| 16 | ||
| 17 | <ul><tt> | |
| 18 | <font color="#0000FF">#include "mmi.h"</font> | |
| 19 | <p>typedef int (*<i>mmi_access</i>) | |

| 26 | <h4> | |
| 27 | DESCRIPTION</h4> | |
| 28 | ||
| 29 | <ul>Creates a mapping for <i>obj</i> at <i>base</i> for <i>size</i> bytes.</ul> | |
| 30 | <ul>CPU I/O space accesses in this range call <i>access</i>, with <i>obj</i> and parameters for the I/O access.</ul> | |
| 31 | ||
| 32 | <h4>RETURN VALUES</h4> | |
| 33 | ||
| 34 | <ul>Returns true if successful.</ul> | |
| 35 | ||

| 42 | { | |
| 43 | SerengetiConsole* s = (SerengetiConsole*) obj; | |
| 44 | return s->access(cpu_id, obj, paddr, wr, size, buf); | |
| 45 | } | |
