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: 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.
