1) The GPU firmware loads off the VFAT partition (google for exactly
what the various files do)
2) the firmware then loads the "kernel" if it's specified in the
config.txt or else the defaults
3) u-boot loads
4) u-boot then boots what it finds, in the case of ARMv7 this is the
linux kernel based on the extlinux.conf file, in the case of aarch64
this is grub using the uEFI implementation in u-boot.
