i.Mx8mm 改1g ddr4

[shaotang]

我按照MX8Mmini_4.14.78_ga_BootLoader_V1-20190118_chn.pdf 修改了uboot中的ddr参数，改为了1gb的ddr4，ddr-timing.c时使用Config Tools for i.MX v10制作的，连接usb启动后log如下：

（mchunkptr p addr is 42200000
inuse(p)=1
next=42201340
mchunkptr p addr is 42200000
inuse(p)=0
next=42200ff0

以及数字是我设置的断点打印）

我是不是漏改了一些东西？请给予我一些帮助，万分感谢！
