      I know ARC and top show the actual full memory but I can never get them to add up to the correct binary memory value.

          My goal is to get it to add up to 4GB binary value. Anyone ever try to do that?

                  Yes, that's the expected value in the 2100:

                  real memory = 3602862080 (3435 MB)
                  avail memory = 3462533120 (3302 MB)
                  

                  The memory map from the SoC provides 32bit access so it sees 3.6GB.

                      Hello!

                      Something like...

                      dmidecode -t memory | egrep "Maximum Capacity|Number Of Devices|Size|Type:"
                      

                      ...can be useful.

                      John

                              There are some things you can see from uboot. Firstly that at boot it reports:

                              Model: Silicom Rogue-2
                                     CPU     1200 [MHz]
                                     L2      800 [MHz]
                                     TClock  200 [MHz]
                                     DDR     750 [MHz]
                              DRAM:  3.4 GiB
                              

                              You can check the board info:

                              Marvell>> bdinfo
                              arch_number = 0x00000000
                              boot_params = 0x00000100
                              DRAM bank   = 0x00000000
                              -> start    = 0x00000000
                              -> size     = 0x04000000
                              DRAM bank   = 0x00000001
                              -> start    = 0x05400000
                              -> size     = 0x7AC00000
                              DRAM bank   = 0x00000002
                              -> start    = 0x80000000
                              -> size     = 0x40000000
                              DRAM bank   = 0x00000003
                              -> start    = 0xC0000000
                              -> size     = 0x10000000
                              DRAM bank   = 0x00000004
                              -> start    = 0xE0000000
                              -> size     = 0x08000000
                              baudrate    = 115200 bps
                              TLB addr    = 0x7FFF0000
                              relocaddr   = 0x7FF36000
                              reloc off   = 0x7FF36000
                              irq_sp      = 0x7F623350
                              sp start    = 0x7F623350
                              Early malloc usage: 228 / 2000
                              fdt_blob = 000000007f623360
                              

                              And adding up those sizes gives 0xD6C00000 = 3602907136 = 3.6GB = 3.35GiB
