NXP i.MX 8M Mini平台Linux系统启动时间优化
0x0 芯片功能介绍
i.MX 8M Mini是恩智浦首款采用先进的14LPC FinFET工艺技术打造的嵌入式多核异构应用处理器。i.MX 8M Mini系列处理器集合了高性能计算、能效、增强的系统可靠性和嵌入式安全性，以推动快速增长的边缘节点计算、流媒体和机器学习应用的增长。
i.MX 8M Mini核心是一个可扩展的核心复合体，由多达4个运行频率高达2GHz的Arm Cortex-A53核心加上基于Cortex-M4 400MHz的实时处理核心组成。i.MX 8M Mini核心选项针对低功耗进行了优化，但提供了消费类、音频、工业、机器学习培训和推断等一系列云服务商所需的广泛处理能力。i.MX 8M Mini还内置硬件1080p视频加速功能，以实现双向视频应用，2D和3D图形提供丰富的视觉HMI体验，以及先进的音频功能，以实现音频丰富的应用。i.MX 8M Mini系列提供广泛的高速接口选择，可实现更广泛的系统连接，并针对工业级认证，可用于任何一般的嵌入式消费和工业应用。
0x1 系统启动时间
在嵌入式产品开发中，不同产品的应用场景对启动时间有不同的要求，大部分产品来说，能更快的启动设备进入工作状态是很有必要的。而且在用户体验角度上，产品的上电启动时间越短，能更快的进入工作状态，是大部分用户对产品的期望。同样，在使用i.MX 8M Mini芯片平台开发产品时，就需要对系统启动速度做一些优化，以达到应用场景的需要。
Linux系统的启动大体可以分为三个部分，Bootloader部分，Kernel部分，RootFS部分。
Bootloader部分，是芯片在上电后运行的第一段用户端的程序，用来初始化芯片的基础操作，并且加载和引导Kernel镜像文件。
Kernel部分，是Linux Kerrnel的启动过程，对预定义的设备初始化并挂载文件系统。
RootFS部分，Linux Kernel启动完成后，需要挂载文件系统，并启动第一个用户进程，即Init0进程。这样后续的其他应用或服务才被启动和运行。
理解了Linux系统的启动流程，就可以在这三个部分上做一些优化，缩减启动时间。本次我们使用了两款硬件平台来测试，分别是米尔科技的MYD-C8MMX开发板和飞凌的OKMX8MM开发板。
MYD-C8MMX开发板的板载系统启动时间是13.5s。
OKMX8MM开发板的板载系统启动时间是15.04s。
下面是MYD-C8MMX板载系统的启动时间统计

[13.569444 0.014471] myd-imx8mm login:下面以MYD-C8MMX开发板为例，我们对Linux系统的三个部分进行优化，优化的内容如下
Bootloader部分
- 取消auto boot timeout
- 移除不需要的驱动和启动方式
- 缩减bootcmd的启动命令参数
Kernel部分
- 移除不需要的驱动模块
- 对于非启动必要驱动，可以改变builtin为module方式来加载
- 添加quiet参数到启动参数，减少不必要的kernel输出信息
RootFS部分
- 从systemd中移除不需要的service
- 固定网络设备的配置信息，禁用systemd network服务
- 对于不需要的service，可以先禁用，等应用启动后再启用
优化后的Linux系统启动时间统计
