上述配置是否正确？
我在imx6q外面挂载了8颗这样的ddr芯片，一共是4GB*8
测试工具显示这样对吗：
=======DDR configuration==========
BOOT_CFG3[5-4]: 0x01, Fixed 2X32 map.
DDR type is DDR3
Data width: 64, bank num: 8
Row size: 16, col size: 10
Both chip select CSD0 and CSD1 are used
Density per chip select: 4096MB
==================================
每次测试都会把imx6q弄的死机，usb直接断了。
