EFITools Ported To 32-Bit To Work With Secure Boot On Intel's Quark SoC

While James Bottomley's efitools package has traditionally been x86_64-only, he ended up porting the package to x86 32-bit in order to handle bringing up UEFI Secure Boot on the Intel Quark SoC board.

Bottomley shared that with efitools 1.5.2 it's tested and works for IA32. He's been using it with the Quark SoC board via the Galileo Kipps Bay D. He's been playing with the Intel Quark and will share more in a future blog post.

EFITools provides various open-source functionality for manipulating UEFI Secure Boot keys and settings. Details on the 32-bit port were shared via this blog post.

The Intel Quark Galileo Development Board.

Intel's Quark is 32-bit x86 only and designed for very small form factors with low power consumption requirements -- including wearable devices. The current range of Quark "Clanton" SoCs are made on a 32nm process and run at 400MHz while having a 2.2 Watt TDP. For those interested there are Linux benchmarks of the Quark-based Edison Module and Intel's Quark X1000 On The Galileo Board benchmarks.
