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.
