[coreboot] Incorrect time stamps on Olive Hill (was: Board status upload of AGESA board like ASUS F2A85-M)

[Zheng Bao]

I tried with gcc 4.9.2 and got same result.
No need to upload the log file.

Thank you very much!

It looks like something else regressed on Olive Hill. At least I doubt
that ramstage just takes 184 ms.

In the past it looked like below.
 
```
$ more amd/olivehill/4.0-7005-gb9a0809/2014-10-08T13\:44\:17Z/coreboot_timestamps.txt 
10 entries total:

  90:load payload                  5,574,542 (325,251)
  99:selfboot jump                 5,674,034 (99,491)
```
 
So I am actually not able to see if there is the same problem with
Olive Hill as with the ASRock E350M1.
 
 
Thanks,
 
Paul
