RISC-V FPGA Board - increase memory in DTS file

HI Team
I'm working on updating the FPGA board memory available within the
RISC-V Linux operating system from 120 MB to a higher value.
The board currently has a DDR4 2GB memory chip inside it.
The DTS file's current settings for memory are shown below and it is
working fine.
memory at 80000000 {
device_type = "memory";
reg = <0x00000000 0x80000000 0x00000000 0x10000000>;
}
When I update the memory settings to double it as shown below, the
Linux isn't booting. The DTS file configuration is printed on screen
and it hangs after that step. Attached log for reference
memory at 80000000 {
device_type = "memory";
reg = <0x00000000 0x80000000 0x00000000 0x20000000>;
}
Note: When i decreases the memory the values are reflecting in RAM
size and its working
