QorIQ PBL: what are ALTCBARH, ALTCBARL and ALTCAR

In the Reference Manual of the QorIQ LS1021a, in section 8 about the Pre-Boot Loader, there are references about "ACS: Alternate Configuration Space", and ALTCBARH ALTCBARL and ALTCAR.

I can't find any information about any of these on any documentation.

 

I'm trying to learn about secure boot for this board and my current RCW+PBI (from NXP SDK 1.9) contains PBI instruction about updating ACS. Since I don't know what this is I am lost.

 

Can anyone explain what these are, or give me pointers to the relevant documentation ?

 

Best,

V.
