Hello,
Tried to take on this challenge with very moderate success. That is not 
surprising being a complete NOOB in regards to UEFI and never doing more than 
the usual-user stuff with GRUB. (So bear with me and have a little patients..) 

I am working with FC29 (Kernel 4.18.16-300) now, if it is better to work with 
FC28 please comment on that. 

Did not dive in detail into the necessary bootloaders and additions (fib/create 
??) to main-line uboot because I nicked two apparently working boot-loading 
stacks from other distros. One originates from a (UEFI) booting Suse image and 
one from a Arch Linux ARM package (2). Cross checked the Alarm bootloaders with 
the Suse image which booted with it. Looking at the PKGBUILD it is a pristine 
as you can gat and decided to go with it for the time being.


The autoboot was unsuccessful with both bootloader-stacks with more or less the 
same errors:
## Starting EFI application at 01080000 ...
System BootOrder not found.  Initializing defaults.
Could not read \EFI\: Invalid Parameter
Error: could not find boot options: Invalid Parameter
start_image() returned Invalid Parameter
## Application terminated, r = 2
EFI LOAD FAILED: continuing...

See  autoboot ‘alarm-mainline-uboot’  and  ‘autoboot suse-uboot’ (1) for full 
logs

After stopping autoboot and loading grub manual form the u-boot shell:
(see ‘manual booteufi’ (1))

=> load mmc 0:2 ${fdt_addr_r} /dtb/amlogic/meson-gxbb-odroidc2.dtb
=> load mmc 0:1 ${kernel_addr_r} /EFI/fedora/grubaa64.efi
=> bootefi ${kernel_addr_r} ${fdt_addr_r}

The kernel does boot and starts system (PID 1) to stop there. 
see also (1) ‘kernel boot’ 

Meanwhile I added :
console=ttyAML0,115200n8 earlycon 
to the kernel cmdline and removed Plymouth entirely to see as much as possible 
on the serial-monitor.

First things first:
How do I get the EUFI autoboot playing along without compiling a u-boot script 
with the above commands which led to load grub ?

And to be frank I am a bit stuck right now..
- Is system unable to (re)mount the initrootfs ?
- Does my serial monitor die on me?

All suggestion are welcome! 

Thaks and greeting Mark
