i MX8M System Boot- IVT

I found out from the datasheet that the IVT offset is 0x8400 (sector 66) if the boot device type is SD/MMC.  

The image I build decodes into following entries at 0x8400

Header: D1 00 20 41

Entry: 00 00 C1 32

reserved1: 00 00 00 00

dcd: 00 00 00 00

boot data: 20 70 C2 32

self: 00 70 C2 32

csf: 40 70 C2 32

reserved2: 00 00 00 00

 

Figure 6-18 from Reference manual says Entry, boot data, and self points to the locations in dest memory.

 

What is the destination memory? Is it RAM? If so then none of those address matches with the address map of DDR.

How should I understand those address?

 

Also Figure 6-3. Internal ROM and RAM memory map is missing from the reference manual

 

Thanks

Bharat
