Could you point to the source of this information? What kind of boot reliability problems should be expected?

I intended to store u-boot in the spi flash, configured to boot from external SD card first and from the eMMC next. For example it may check for presence of /boot/uEnv.txt on the external card first and on the eMMC next. This could allow experimenting with different OS-es without the need of a screwdriver whenever PBP is bricked due to incorrect boot configuration of the eMMC.
