/*
* S100 UART utest 说明
*
* 1. 本测试面向当前 BSP 的 UART v2 驱动实现，覆盖非控制台串口的基础访问流程。
* 2. 根据 BSP 约定，uart4 默认为 msh 控制台，本测试不会对 uart4 做 open/read/write
* 覆盖，避免干扰交互终端。
* 3. 测试对象仅包含启用的 uart5 和 uart6；若两者都未使能，测试会打印跳过提示。
* 4. 测试分为两部分：
* - basic：验证 rt_device_find/open/control(close) 这条基础控制路径；
* - txrx smoke：验证配置成功后能够执行一次 write，并检查 read 接口可调用。
* 5. 当前 S100 UART BSP 不支持 DMA，因此这里不覆盖 DMA 模式。
* 6. txrx smoke 现在要求被测串口具备回环条件（硬件短接 TX/RX 或外部回环），测试会校验
* 接收到的数据内容与发送 payload 完全一致。
