I would describe it differently:

 - firmware finds bootloader "somewhere" on some ESP, bootloader finds
   boot.cfg in the same directory (if it exists)
 - otherwise bootloader guesses a partition from where the kernel is
   loaded and also checks for a boot.cfg in the root directory of that
   partition. The bootme flag may be involved in this step (but is not
   required).
 - kernel gets passed the location where it was loaded from and optional
   other arguments if boot.cfg was found. kernel decides what to use
   as root partition. A /boot.cfg on this partition is not needed nor
   usefull unless it happens to be the same partition as where the kernel
   is loaded from (the item before) and there was none in the ESP
   directory (the first item).
