Minnowboard is the platform for UEFI development and supports UEFI capsule update since 0.99, and we are supposed to be able to test the feature with fwupd. However, there is no capsule file in fwupd.org or the official firmware download site. Besides, the Minnowboard firmware source in the current edk2/edk2-platforms git couldn't build due to the recent change of directories. My goal is to rebase the Minnowboard build system to the current git master and create a working up-to-date firmware. Signing the firmware properly would be a plus so that we can apply a private repo in fwupd.org for the development or QA testing.
