AM62A7: 8GB DDR Support

Part Number: AM62A7

Tool/software:

Dear TI Team,

Currently I'm working with L6.1.46-SDK_9.1.
The AM62A7 CPU supports 8GB DDR. So i was trying to boot with 8GB DDR.

I have updated the k3-am62a-ddr-1866mhz-32bit.dtsi file as of 8GB DDR. Also updated the memory node as below in uboot DTS file.

        memory@80000000 {
                device_type = "memory";
                /* 8G RAM */
                reg = <0x0 0x80000000 0x0 0x80000000>,
                      <0x8 0x80000000 0x1 0x80000000>;
        };

Is the above configuration is proper ?

While booting I'm getting the DRAM size as below.

DRAM:  2 GiB (effective 8 GiB)

What does this 2 GiB (effective 8 GiB)  means? From where we are getting these prints ?

Kindly reply asap.
