源码压缩包的文件路径：/home/alientek/mp13x_pro/stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/sources/arm-ostl-linux-gnueabi/tf-a-stm32mp-v2.6-stm32mp1-r1-r0

终端输入指令：

tar -xvf tf-a-stm32mp-v2.6-stm32mp1-r1-r0.tar.xz

解压完成：

（2）打补丁，获取stm32mp135的源码

终端输入指令：

cd tf-a-stm32mp-v2.6-stm32mp1-r1
for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

打补丁完成：

（3）设计编译脚本build.sh

1、进入tf-a源码：

终端输入指令：

 cd tf-a-stm32mp-v2.6-stm32mp1-r1/

2、创建build.sh脚本文件

终端输入指令：

touch build.sh
chmod 777 build.sh

3、编辑build.sh脚本

终端输入指令：

vim build.sh

输入以下内容：

#!/bin/sh
# script-name: build.sh
# version: 1.0
# date: 2023-06-15
# author: wangjianquan

#删除上层目录的编译文件
rm ../build/ ../deploy/ -rf

#运行编译
make -f ../Makefile.sdk all

保存文件，按下键盘的Esc键，输入:wq!

二、修改TF-A源码

1、创建设备树

源码文件目录：tf-a-stm32mp-v2.6-stm32mp1-r1/fdts
终端执行命令：

cp stm32mp135d-dk.dts stm32mp135d-mini.dts
cp stm32mp13-pinctrl.dtsi stm32mp13-pinctrl-mini.dtsi
cp stm32mp135d-dk-fw-config.dts stm32mp135d-mini-fw-config.dts

解释：这里是以stm32mp135d-dk板子的官方源码为模板进行的移植，文件名中含有"mini"字样的都是我们接下来要进行源码处理的文件，也就是我们开发板的DIY源码！

2、修改源码：fdts/stm32mp135d-mini.dts

（1）修改pinctrl头文件路径

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：使我们新建的pinctrl文件在设备树中生效。

（2）修改model和compatible属性

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：model属性在tf-a启动时会被调用显示在串口输出打印消息里，调用文件：plat/st/stm32mp1/bl2_plat_setup.c；compatible属性用于platfrom的匹配，这个属性调用的文件数量较多，这里不一一列举，自行在源码文件夹中搜索。

（3）删除不需要用到的uart节点

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：板子是靠uart4进行串口通信的，其它串口我们可以预留到别的功能上！这里不建议大家使用别的uart进行串口通信，因为st官方设计的源码里面指定是使用uart4的，如果你换了别的uart，会加大你对源码修改的工作量。

（4）修改设备树电源管理

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：ST官方提供专用的PMIC（型号：STPMIC1A）成本太高，我设计的开发板里没有用到这个玩意，我也不建议大家去使用，毕竟1000片起订1.9美元/片！STPMIC1A 是一个 IIC 器件，所以也会存在IIC节点，这里我们直接删除。ST官方提供的tf-a、optee、uboot、linux kernel中都有关于这个PMIC使用的设备树配置，接下来的教程里，在设备树中我们都将涉及到取消与这个PMIC相关的配置的操作。

（5）修改EMMC设备

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：ST官方的源码里没有使用到sdmmc2（TF卡），所以这里补充上了sdmmc2的节点，这里没什么好说的。

（6）删除时钟

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：我的开发板上用到了有源晶振来代替从mp135芯片上获取的时钟分频，所以注释掉这个节点了，你可以试着注释掉这个节点，如果启动tf-a的时候报错了再恢复这个节点就行。

#define DDR_SIZE	0x20000000 /* 512MB */

5、修改源码：drivers/st/clk/clk-stm32mp13.c

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：在设备树中我们注释了clk节点，这里做对应的处理！

clk-stm32mp13.c 修改的部分源码

static void clk_oscillator_check_bypass(struct stm32_clk_priv *priv, int idx,
					bool digbyp, bool bypass)
{
	struct clk_oscillator_data *osc_data = clk_oscillator_get_data(priv, idx);
	struct stm32_clk_bypass *bypass_data = osc_data->bypass;

	if ((mmio_read_32(address) & RCC_OCENR_HSEBYP) &&
	    (!(digbyp || bypass))) {
		// panic();
	}
}

三、修改Makefile.sdk*

←（左侧）：已修改的tf-a源码
→（右侧）：未修改的tf-a源码

解释：编译我们为板子重新设计的设备树。

解释：修改编译器为arm-none-linux-gnueabihf。

解释：关闭tf-a的关联编译。
