Hi, The flashing method for booting from eMMC for arndale is available in https://wiki.linaro.org/Boards/Arndale/Setup/EnterpriseUbuntuServer?action=A...
This should be done after applying the patch http://lists.linaro.org/pipermail/boot-architecture/2013-February/000220.htm... on http://git.linaro.org/gitweb?p=arm/uefi/uefi-next.git%3Ba=shortlog%3Bh=refs/...
The document is also attached.
