Dear Zheng,


Thank you very much!

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

```

Total Time: 184
```

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:

  10:start of ramstage             3,738
  30:device enumeration            14,178 (10,439)
  40:device configuration          479,198 (465,020)
  50:device enable                 2,381,475 (1,902,276)
  60:device initialization         2,689,928 (308,453)
  70:device setup done             3,440,623 (750,694)
  75:cbmem post                    5,244,342 (1,803,719)
  80:write tables                  5,249,290 (4,948)
  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
