We had a wonderful Linaro UEFI mini-sprint at Cambridge from 11-13 Dec and fixed a lot of lingering problems like a home for all the board support for edk2(UEFI) on Arm. Ryan has set up a common tree for all the boards git://git.linaro.org/arm/uefi/uefi-next.git This is going to be the de-facto upstream for UEFI on Arm. Grant, Oliver with Ryan reflected on the maintainership structure for UEFI on Arm. Leif worked hard to natively build the UEFI on Arm to get rid of x86 from his life, which he has almost done using his hacked chromebook running Debian—a loyal Arm and Linaro employee!
I worked to build it for the latest tool chain as I always end up using old tool chains resulting code breaking in latest tool chains. There was a lot of planning and discussions related to UEFI on Arm led by Andrea.
The UEFI boot loader LEG has ported to Arnadle is capable for microSD boot now. We are working to add SATA and network boot support on it now. The binary and setup for the Arndale is available here https://wiki.linaro.org/Boards/Arndale/Setup/UEFI.
