工具与软件：
您好、工程师
我尝试将 DDR 修改为4GB、并修改了 k3-am62x-sk-common.dtsi、k3-am625-sk.dts：
内存@8000000｛
device_type ="存储器"；
/* 4G RAM */
REG =<0x00000000 0x80000000 0x00000000 0x80000000>
<0x00000008 0x80000000 0x00000000 0x80000000>；
}；
启动日志如下：μ A

它显示：
DRAM： 2GiB (有效4GiB)
我不确定它是否可以在4GB 模式下工作？
如果我修改了 SysConfig 后的 k3-am62x-sk-ddr4-1600MTs.dtsi、它会显示：
U-Boot SPL 2024.04 (2024年11月6日- 22：53：09 +0800)
SYSFW ABI：4.0 (固件版本0x000a '10.0.8--v10.00.08 (Fiery Fox)')
SPL 初始堆栈使用：13392字节
那么、这里还有其他问题吗？
谢谢！
