? 
I ?am working on ?mpc8548cds board ? 
? 
Feature : POST DIAGNOSTICS; 
? 
In ?u-boot :? post/memory.c,cpu.c..etc.. 
? 
Need your suggestion? 
? 
There is function pointers in post.c which calls the respective function to perform diag test ( example ram , cpu, ether ..etc ) which will be picked from tests.c ( This is the structure which defines all the fileds of the tests) 
? 
Function pointer defined in post.c 
? 
static int post_run_single (struct post_test *test, 
??????????????????????????????????????????????????????? int test_flags, int flags, unsigned int i) { 
? 
.. 
if ((*test->test) (flags) != 0) {???????????? ( This function pointers will call cpu tests from post/cpu.c defined below based tested entered from u-boot promt ?) 
? post_log ("FAILED\n") 
} else { 
post_log ("PASSED\n") 
} 
? 
------------------------------------------------------------------------------------------------------------ 
CASE 1 Experiment : 
Post/cpu.c 
? 
int cpu_post_test (int flags) 
{ 
??????? int ic = icache_status (); 
??????? int? ret = 0; 
??????? int c; 
??????? post_result_cpu = 0; 
??????? cpu_dbg = 0; 
??????? boot_flag_post = 0; 
? 
?????? printf( ? Testing cpu diag \n?);?? ? TRAP IS Generated and box got rebooted. 
? 
?????? Other part of code exits.. 
}
