For a planned new SoC in this SoC family, the base address of the DRAM will be changed from 0x80000000 to 0x20000000.
The PIE support will be useful to maintain multiple similar SoCs whose DRAM addresses are different.
Now CONFIG_SYS_TEXT_BASE is not important. I just set it to 0 to ensure CONFIG_POSITION_INDEPENDENT is working.
