自己记的笔记，详细内容请参考正点原子教程STM32MP1 嵌入式 Linux 驱动开发指南2.0。
1. TF-A移植：
1.1 新建开发板的设备树
VSCODE 打开 tf-a-stm32mp-2.2.r1\fdts 目录并且打开终端
复制这两个文件stm32mp157d-ed1.dts，stm32mp15xx-edx.dtsi 为atk，我测试了qcy不能用。。。
cp stm32mp157d-ed1.dts stm32mp157d-atk.dts
cp stm32mp15xx-edx.dtsi stm32mp157d-atk.dtsi
头文件名称也要修改
1.2 修改设备树电源管理
打开 stm32mp157d-atk.dtsi 文件，第 54~281 行的内容全部删除掉，pmic节点信息内容全部删除。
将上面vin 节点内容全部删除掉，也就是将 17~23 行代码删除掉，替换为下面的
代码：
vddcore: regulator-vddcore {
compatible = "regulator-fixed";
regulator-name = "vddcore";
regulator-min-microvolt = <1200000>;
regulator-max-microvolt = <1350000>;
regulator-off-in-suspend;
regulator-always-on;
};
v3v3: regulator-3p3v {
compatible = "regulator-fixed";
regulator-name = "v3v3";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-off-in-suspend;
regulator-always-on;
};
vdd: regulator-vdd {
compatible = "regulator-fixed";
regulator-name = "vdd";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-off-in-suspend;
regulator-always-on;
};
vdd_usb: regulator-vdd-usb {
compatible = "regulator-fixed";
regulator-name = "vdd_usb";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-off-in-suspend;
regulator-always-on;
};
1.3修改TF卡和EMMC设备树
继续操作 stm32mp157d-atk.dtsi 这个文件，找到“sdmmc1”和“sdmmc2”这 2 个节点。
将 sdmmc1 和 sdmmc2 节点改为如下所示内容:
&sdmmc1 {
pinctrl-names = "default";
pinctrl-0 = <&sdmmc1_b4_pins_a &sdmmc1_dir_pins_a>;
st,neg-edge;
broken-cd;
bus-width = <4>;
vmmc-supply = <&v3v3>;
status = "okay";
};
&sdmmc2 {
pinctrl-names = "default";
pinctrl-0 = <&sdmmc2_b4_pins_a &sdmmc2_d47_pins_a>;
non-removable;
st,neg-edge;
bus-width = <8>;
vmmc-supply = <&v3v3>;
vqmmc-supply = <&v3v3>;
status = "okay";
};
1.4 修改USBOTG设备树
继续操作 stm32mp157d-atk.dtsi，找到
“usbotg_hs”这个节点。
将 usbotg_hs 节点改为如下所示内容：
并文件里面添加了一个名为“usbphyc”的节点。
&usbotg_hs {
phys = <&usbphyc_port1 0>;
phy-names = "usb2-phy";
usb-role-switch;
status = "okay";
};
&usbphyc {
status = "okay";
};

注意 ELF_DEBUG_ENABLE=，1 不是单引号，是tab键上面的一个键。
