16 | * This is common routine to manage secure monitor API | |
17 | * used to modify the PL310 secure registers. | |
18 | * 'r0' contains the value to be modified and 'r12' contains | |
19 | * the monitor API number. It uses few CPU registers | |
20 | * internally and hence they need be backed up including | |
21 | * link register "lr". | |
22 | * Function signature : void omap_smc1(u32 fn, u32 arg) | |
