AFAIK, the Linux kernel's EFI stub boot loader only works on x86 and
x86-64 platforms, but the device path you've provided suggests you're
using ARM ("gArmPlatformTokenSpaceGuid...."). Thus, you probably won't
get this to work, unless of course I'm mistaken about the architecture
issue.
Instead, you'll need to use ELILO, Fedora's patched GRUB Legacy, or GRUB
2 to launch the Linux kernel. I'm not sure which of these will work best
on ARM; it's conceivable that one or more won't work on ARM.
