RT1050 bootloader to check SD card then boot from XIP?

All of the boot options I have seen for the rt1050 require using the actual boot_mode pins with a switch or jumper to select the boot source. 


If I am looking for the best way to handle firmware updates in the field, by an end user, is a switch controlling boot_mode the best way to go?


Ideally I was thinking the bootloader would first check for an update file on the SD and then update if needed, otherwise continue booting from XIP without using the boot_mode pins at all.  Similar to the process described here for AVR: SD bootloader


Any ideas appreciated.
