   Also remember that GRUB depends on BIOS or UEFI, and the former is x86-   
   specific -- not sure about the latter.   
      
   Basically, every vendor’s ARM chipset came up with its own way of booting.   
   In the absence of a BIOS-style interface for querying what hardware is   
   available, the Linux kernel is built with a “device tree” structure that   
   hard-codes this information for your specific chipset.   
      
   There is now an equivalent spec standardized for the ARM world (adaptation   
   of UEFI??), but I understand this is only in use on servers with AArch64,   
   and the Raspberry Pi predates it anyway.
