Some while ago did some work on this, resulting in a prematurely image with a at the time of creation latest kernel 4.18.16-202.
It was not my intention to make a aarch64 image for a RPI, nor will it be in the future;
Just out of "academic curiosity " installed bcm283x-firmware and rpi3-u-boot.bin to try to boot it with a RPI. And it did :)
_Note_ this is far from anything decent at least it boots :) (1)

It boots very slow! Especially on a RPI going through bootcode.bin > uboot > grubaa64.efi > grub2 > kernel
The kernel is cross complied from the equivalent community-kernel source package Pablo made for armhfp with the command (in which you may ignore --define="dist .ns7") :
rpmbuild --ba --target aarch64 --with=cross --without=perf --without=tools --without=debuginfo --define="dist .ns7" --define="_arch aarch64" --define="_build_arch aarch64" --define="__strip /usr/bin/aarch64-linux-gnu-strip" kernel.spec
cross tools installed:
$ rpm -qa | grep aarch64
binutils-aarch64-linux-gnu-2.27-9.el7.1.x86_64
gcc-aarch64-linux-gnu-4.8.5-16.el7.1.x86_64
gcc-c++-aarch64-linux-gnu-4.8.5-16.el7.1.x86_64
It's on my todo list to get this to a next level;
Maybe we can cooperate on this, though (as said before) it's not my intend to create (maintain) aarch64 RPI images.
AFAIK now, are some of the issues to be dealt with:
* uboot-images-armv8 carry a fedora specific patch causing uboot to look in /EFI/fedora for grubaa64.efi
* obviously grubby has no understanding for the device-tree on aarch64 and most likely will never have this.
* livecd tools, used by the application tools to create images for armhfp has no aarch64 support. (2)
* probably a lot more...

(1)l link to kickstart file used to create image :
https://github.com/markVnl/nethserver-createimg/blob/ks_wip/ks/Centos-Uboot-aarch64.ks
(2) patch to provide basic aarch64 support for livecd tools / imgcreate,
_Note_ it does not provide full support, among other things EFI/centos/grub.cfg is not created...
