UEFI on Arm: A Comedy of Bootloads and Secure Boot Bloopers
What does UEFI look like from an Arm perspective? Picture this: UEFI trying to fit into Arm’s world like a penguin in a desert—awkward yet determined. With u-boot playing mediator, Arm devices get a taste of Secure Boot, but not without some key-signing shenanigans. Arm’s UEFI journey is a comedic epic!

Hot Take:
UEFI on Arm: The spicy firmware salsa that’s trying to tango with Linux, but keeps stepping on its own toes. While x86 is out here rocking the Secure Boot like it’s the latest dance move, Arm is still trying to find its rhythm. Will it ever catch up? Maybe, but not without a few missteps and some serious choreography lessons from the Linux community.
Key Points:
- UEFI originally an Intel brainchild, now a standard for x86 but a mixed bag for Arm.
- Secure Boot has been a Linux headache, especially with Windows 8’s certification requirements.
- Shim serves as the magic key for Secure Boot in the x86 world but needs some DIY on Arm.
- U-boot is the bootloader hero for Arm but comes with its own set of challenges.
- Linux distributions are making strides, but Red Hat is still doing the two-step with its own keys.
