What are the addresses set in the device tree (mentioned in PG252)?
I am checking the address editor of the zcu104 2020.1 BSP in vivado, I saw that all 5 ports of the vcu_ddr4_controllers are mapped to the address "0x48_0000_0000". Also I found out that when I want to enable the PL DDR for VCU decoder (pg252 page 85), I need to add some memory changes to the device tree as below:
I wanted to know if these two addresses are related and if so, why is the address in the device tree 0x48 and not 0x48_0000_0000?
Also I wanted to know if these addresses have anything to do with the M_AXI_HPM1_FPD on table 10-1 of ug1085. I would really appreciate any info on this memory addresses.
