(ARM Cortex-A7) T113-S3 (MangoPi MQ-R)

build kernel 6.0.1

---

參考資料：
1. awboot
2. whycan
3. debugdump

如下：

$ cd
$ git clone https://github.com/Evlers/linux_kernel_t113
$ cd linux_kernel_t113
$ make mangopi_dual_t113_defconfig
$ make zImage dtbs modules -j4

P.S. arch/arm/boot/zImage、arch/arm/boot/dts/sun8i-t113-mangopi-dual.dtb

預設使用UART5作為除錯界面，如果要改成UART0，需要做如下修改
