i.MX 6 serial downloader is not necessarily booting via UART but can also boot from USB. In fact only some i.MX chips have serial downloader support via UART (e.g. 6UL/ULL and Vybrid) but all of them have serial downloader support via USB. Use the more appropriate BOOT_DEVICE_BOARD define which is used for ROM provided recovery mechanisms in general.

Returning BOOT_DEVICE_UART here makes the SPL to load U-Boot from the debug UART using a ymodem transfer when enabled with CONFIG_SPL_YMODEM_SUPPORT like it is on the OPOS6ULDev board. This is now broken.
