Braswell: FSP Integration Guide of-of-date #16

Closed miczyg1 closed 5 years ago

miczyg1 commented 5 years ago

The Braswell FSP Integration Guide states that the base address for FSP binary is 0xfff20000. However, current MR2 release FSP binary base address is 0xfff9c000. Could You please update the documentation or the binary?

0xfff20000 is the base address for the regular version of BSW FSP. 0xfff9x000 is the base address for the Secure Boot version of FSP.

There is a build flag that controls which version of the FSP binary is generated at compile time.

I believe the confusion comes from the fact that the MR1 release gave a regular build whereas the MR2 release gave a Secure Boot build. We have posted updated versions of BSW FSP (1.1.7.0 and 1.1.8.0) and we were careful to give both the regular and Secure Boot versions of the BSW FSP binary this time.

We have also updated the FSP integration guide to clarify that each version has a difference base address. Hope that helps.
