RK3568-ANDROID11-4G-EC20-系统篇（移远模块）
首先，要先获得技术支持
步骤一，先在USB模块上完成4G
步骤二，移植到PCIE座子上
磨刀不费砍材功，请先拿到技术文档支持，我的参考是：Quectel_Android_RIL_Driver_V3.3.62_master_beta(支持EC200A).tgz
主要文件：Quectel_Android_RIL_Driver_V3.3.62_master_beta(支持EC200A)\libquectel-ril\arm64-v8a\libreference-ril.so
主要文档：Quectel_Android_RIL_Driver_User_Guide_V2.0.pdf

系统部分：
1.添加rild库（\libquectel-ril\arm64-v8a\libreference-ril.so）
改名成：librk-ril.so
预制到：\device\rockchip\common\4g_modem\lib64\librk-ril.so
代码要清理重新编译，有遇到没有更新库的情况，更新后大编才可以
2.更新已下文件

\vendor\rockchip\common\phone\etc\ppp\ip-down
\vendor\rockchip\common\phone\etc\ppp\ip-up
\vendor\rockchip\common\phone\etc\ql-ril.conf
\vendor\rockchip\common\phone\lib\libreference-ril-ec20.so 3.关闭SELINUX
\device\rockchip\common\BoardConfig.mk
-BOARD_SELINUX_ENFORCING ?= true
+BOARD_SELINUX_ENFORCING ?= false如果卡在android动画，建议看一下降频篇
4.打开BOARD_HAS_RK_4G_MODEM
#enable 3g dongle
BOARD_HAVE_DONGLE ?= false
ifeq ($(BOARD_HAVE_DONGLE),true)

+BOARD_HAS_RK_4G_MODEM ?= true
ifeq ($(strip $(BOARD_HAS_RK_4G_MODEM)),true)
DEVICE_MANIFEST_FILE += device/rockchip/common/4g_modem/manifest.xml
endif
5.去掉property:ro.boot.noril
如果存在电话这一项，就执行下面的内容
设置setprop ro.radio.noril 为true
暂停ril-daemon服务
