This isn't really that strange for an ARM SoC.

Also, there is UEFI firmware for it.

Can this UEFI firmware be ported to other ARM devices, e.g. phones, tablets, books?

Have you checked out uboot?

Doesn't everything under the sun boot with uboot? Uboot is usually what people want to replace when they say "why can't this just run UEFI?"

I have yet to find a valid reason for UEFI to replace u-boot, or UEFI to exist at all.

How can one "discover" something well documented in the datasheet, and on google https://forums.raspberrypi.com/viewtopic.php?t=266130, https://www.google.com/search?q=raspberry+pi+boot+chain

I don't think the author was presenting it like some kind of "new to the world" discovery. It was just something they recently learned.

The blog post from OP is mostly AI generated - quite a few tells in the style of writing.

As an electrical engineer: you'd be surprised how many people "discover" long held truths like that you can use the MPN ("Manufacturer Part Number") of a device to find it's documentation and that this documentation sometimes contains useful data.
