I did not yet try it, but my idea to achieve this is to
have bootcmd be a simple conditional chain containing
all the tests and dependencies, in my case:

fpga loadmk 0 0x54000 && fpga loadmk 1 0x6c0000 && bootm 0x80000 || run_update

Again, this is just the idea I have for my own board, I did
not yet try it! (run_update is what will be our firmware
update function)
