The ARM world is rapidly moving towards UEFI, partly thanks to Microsoft insisting there be something like it for them to build on.
Even better, u-boot implements enough of it to boot a UEFI operating system. So on some new devices you'll get UEFI firmware, on everything else you can flash u-boot with UEFI support... and it's now part of their default configs.
Pretty cool. :-)

Hope it isn't another quirky "just enough to boot windows, with other OSs having to clone windows behaviour to work" thing. Can secure boot be disabled on ARM?

- pjc50 10y agoSee your mobile phone: it depends whether the manufacturer makes that an option. In a processor I'm familiar with (imx53), once it's turned on by a processor fuse it stays on - it's then up to the second stage boot loader (provided by the device OEM) to decide whether to load untrusted images.
