[coreboot] Reducing FSP performance time

[Antony AbeePrakash X V]

Hi,

We are building a FSP integrated coreboot image. We are using Intel FSP 2.0.
While booting the coreboot image we get the following FSP performance data logs.

Coreboot FSP Performance Data

ID: 950 - 951: 2347842343 - 2126500026 --> 170ms

ID: 952 - 953: #^!1175958314 - 3141289776 --> 1792ms

ID: 954 - 955: #^!1702555243 - #^!1465185826 --> 182ms

ID: 956 - 957: #^!1094328449 - #^!1091128442 --> 2ms

ID:952 - 953 is FSP_TEMP_RAM_EXIT which takes around 1.7 sec. Below are the queries:

1.  What is happening in FSP_TEMP_RAM_EXIT phase ?
  2.  Can we reduce this time further ?

Please provide your feedback.

Thanks & Regards,
Antony
