[参考译文] AM625：GPMC NAND 引导的 defconfig

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1432710/am625-defconfig-for-gpmc-nand-booting

工具与软件：

我想使用 AM625为 GPMC NAND 引导构建 tiboot3。

我根据 am62x_evm_r5_defconfig 进行配置、并附加一些配置：

对某些函数(如 spi_mem_exec_op.)的未定义引用发生了错误

您能为 am625提供 NAND 引导的 defconfig 吗？

处理器 SDK：09.02.01.09
