Question

Hy all，

我基于飞思卡尔的i.MX6开发了自己的主板，我想配置设备树。我正在使用此软件：Processor Expert for i.MX来生成所有引脚的配置。该软件正在生成.c和.h文件：

GPIO.c
I2C.c
...
iomux_config.c
iomux_config.h
...

我的问题是：我在linux内核或我的u-boot文件中如何以及在哪里实现这些文件？或者我是否必须生成dts文件？

感谢您的帮助！

编辑：

以下是一些生成的文件：

iomux_config.c：

#include "iomux_config.h"

/*
** ===================================================================
**     Method      :  pin_init_iomux_config (component PinSettings)

/*!
**     @brief
**         This method sets registers according routing settings. Call
**         this method in user code to route desired pins into
