STM32MP157 TF-A 移植
在了解了 STM32MP 系列芯片的启动流程后，我们将开始进行东山 Pi 柒号的 TF-A 移植。
准备工作
首先，我们需要下载 STM32MP1 系列的 STM32MPU_Developer_Package，该包中包含编译器 SDK 和官方源码：
-
STM32MP1 OpenSTLinux 开发套件
https://www.st.com.cn/zh/embedded-software/stm32mp1dev.html -
OpenSTLinux 开发套件安装和使用说明
https://wiki.stmicroelectronics.cn/stm32mpu/wiki/STM32MPU_Developer_Package
完成 SDK 和源码的安装与下载后，我们就可以开始系统移植了。
开始TF-A 移植
解压 SOURCE 源码包，进入tf-a目录：
cd tf-a-stm32mp-v2.8.15-stm32mp-r2-r0
解压 tf-a 源码，并使用st patch文件
tar -xvf tf-a-stm32mp-v2.8.15-stm32mp-r2-r0.tar.xz
cd tf-a-stm32mp-v2.8.15-stm32mp-r2
for p in `ls -1 ../*.patch`; do patch -p1 < $p; done
复制官方开发版stm32mp157d-dk1的设备树作为源，我们在这基础上进行修改。因为板子芯片是stm32mp157dac所以需要使用d结尾的开发板配置。这是芯片后缀不同代表内部外设有差异，需要设备树中选择正确的芯片级stm32mp15x*.dtsi文件：
cp fdts/stm32mp157d-dk1.dts fdts/stm32mp157d-ask.dts
cp fdts/stm32mp157d-dk1-fw-config.dts fdts/stm32mp157d-ask-fw-config.dts
cp fdts/stm32mp15xx-dkx.dtsi fdts/stm32mp15xx-ask.dtsi
修改stm32mp157d-ask.dts，使用我们复制的dtsi：
// #include "stm32mp15xx-dkx.dtsi"
#include "stm32mp15xx-ask.dtsi"
现在我们主要来修改stm32mp15xx-ask.dtsi文件：
DDR 配置修改
在stm32mp15xx-ask.dtsi中的DDR设备树为"stm32mp15-ddr3-1x4Gb-1066-binG.dtsi"，这与我们的板子配置不一样，东山派内存为2x2Gb的组合。在东山派Github上的DDR配置在新版本内核中使用会有些问题，这里我们使用这份DDR配置stm32mp15-ddr3-ask-2x2Gb-1066-binG.dtsi：
#define DDR_MEM_COMPATIBLE ddr3l-ask-1066-888-bin-g-2x2gb-533mhz

#include "stm32mp15-ddr3-ask-2x2Gb-1066-binG.dtsi"
电源调节器修改
硬件说明中核心板采用分立电源，未使用PMIC电源管理：
我们需要修改stm32mp15xx-ask.dtsi中相关的配置：
// 删除 &i2c4 全部配置
&i2c4 {
...
};// 添加固定电压调节器
vdd: vdd
vddcore: vddcore
vdd_usb: vdd_usb
v3v3: v3v3
时钟源修改
核心板使用有源晶振，需要删除digbypass:
// 删除以下节点
&clk_hse {st,digbypass;
};
添加EMMC
&sdmmc2 {
..
};
修改调试串口GPIO

};源码修改
因为在设备树中我们添加了几个regulator-fixed，需要修改tf-a-stm32mp-v2.8.15-stm32mp-r2/plat/st/stm32mp1/stm32mp1_def.h中的PLAT_NB_FIXED_REGUS：
// #define PLAT_NB_FIXED_REGUS U(2)
#define PLAT_NB_FIXED_REGUS U(10)
开始编译
# 需要使用你的SDK路径
source ~/MP157/weston/v5.1/sdk/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi# 设置 FIP 路径
export FIP_DEPLOYDIR_ROOT=$PWD/../../FIP_artifacts# 编译 usb 启动的 tf-a，在USB烧录时使用
make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157d-ask TF_A_CONFIG=usb all# 编译 sd 卡启动程序
make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157d-ask TF_A_CONFIG=optee-sdcard all# 编译 emmc 启动程序
make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157d-ask TF_A_CONFIG=optee-emmc all编译结束的以下错误可以暂时忽略，因为它需要用到OP-TEE和U-boot文件：
[ERROR] some files are not present, please provide it or change the paremeters
编译成功后会生成以下文件，其中带stm32后缀和metadata.bin文件需要烧录到开发板中:
tf-a-stm32mp-v2.8.15-stm32mp-r2$ ls ../deploy/
debug metadata.bin tf-a-stm32mp157d-ask-optee-sdcard.stm32
fwconfig tf-a-stm32mp157d-ask-optee-emmc.stm32 tf-a-stm32mp157d-ask-usb.stm32
开始烧录
解压打开STM32MP1 OpenSTLinux入门套件包，将编译新生成的*.stm32和metadata.bin文件复制到images\stm32mp1\arm-trusted-firmware中，复制images\stm32mp1\flashlayout_st-image-weston\optee\FlashLayout_sdcard_stm32mp157d-dk1-optee.tsv为一份新的配置。如果使用emmc则可以使用FlashLayout_emmc开头的文件，修改如下：
#Opt Id Name Type IP Offset Binary
- 0x01 fsbl-boot Binary none 0x0 arm-trusted-firmware/tf-a-stm32mp157d-ask-usb.stm32
这里的烧录只使用了- usb.stm32表示将TF-A烧录到内存中运行，因为烧录SD和EMMC需要修改uboot，这里暂时跳过。
使用命令行STM32_Programmer_CLI.exe进行烧录运行：
STM32_Programmer_CLI.exe -c port=usb1 -w .\flashlayout_st-image-weston\optee\FlashLayout_sdcard_stm32mp157d-ask-optee.tsv
烧录结束后可看到以下串口打印，这里TF-A已运行成功，并启动USB DFU等待下载文件：
