By calling fdt_chosen(), the chosen node will be updated / created by the "fdt boardsetup" command. This is useful for setting of the kernel commandline via the "bootargs" env variable.
With this change, the "fdt boardsetup" can be used to prepare the DT blob for SPL booting. The patched DT blob can be saved to flash and can be used by the SPL U-Boot version directly for Linux booting.

There are possibly some workflows this breaks. I can't remember if for AMP boot we need to do something between ft_board_setup() and fdt_chosen()
Could you please elaborate what exactly you fear here? Is this a NACK for this patch?
Possibly. I've got to find our docs on how we do 2-core AMP booting sequence w/regards to device tree.
See if this works:
