Thank you for the hints, it Led to a booting setup!
Still need to fine tine, some customization may not be needed howerever this configuration led to the booting odroid HC1.
Appended cpuidle.off=1 console=tty1 console=ttySAC2,115200n8 to the cmdline:
# cat /boot/extlinux/extlinux.conf # extlinux.conf generated by appliance-creator ui menu.c32 menu autoboot Welcome to Centos-Uboot-Community-kernel. Automatic boot in # second{,s}. Press a key for options. menu title Centos-Uboot-Community-kernel Boot Options. menu hidden timeout 20 totaltimeout 600

In an effort to mimic the FC28 intenramfs added/omitted some modules and added _all_ exynos and samsung divers loaded by the booting FC28 setup:
#cat /etc/dracut.conf.d/odroid_hc1.conf add_dracutmodules+="dm" omit_dracutmodules+="network ifcfg" add_drivers+="exynosdrm exynos_bus exynos_trng exynos_nocp exynos_rng phy_exynos_dp_video phy_exynos_mipi_video dwc3_exynos clk_exynos_audss i2c_exynos5 dw_mmc_exynos dw_mmc_pltfm dw_mmc phy_exynos_usb2 phy_exynos5_usbdrd pwm_samsung "
(AGAIN) NOTE: some may be necessary others may be ommited..
Turns out one additional driver - dwc3 - is needed to boot the odroid HC1 with a rootfs residing on a SATA device. My best guess is dwc3_exynos actually depends on dwc3 and/or (one of) the dependencies of dwc3.
#cat /etc/dracut.conf.d/odroid_hc1.conf add_dracutmodules+="dm" omit_dracutmodules+="network ifcfg" add_drivers+=" exynosdrm exynos_bus exynos_trng exynos_nocp exynos_rng phy_exynos_dp_video phy_exynos_mipi_video dwc3_exynos clk_exynos_audss i2c_exynos5 dw_mmc_exynos dw_mmc_pltfm dw_mmc phy_exynos_usb2 phy_exynos5_usbdrd pwm_samsung " add_drivers+=" dwc3"
Mark: how do you get CentOS with this actual kernel on the Odroid HC1 ? I've 2 of them running Fedora as a Mailserver and Nextcloudserver.
The kernel are kindly build by Pablo and can be found at: https://armv7.dev.centos.org/repodir/community-kernel-latest/
On a running armhfp device (distro or kernel should not matter); You may mount the sd-card and chroot in to the card to install / update the kernel.
Mount the rootfs partition (usually part4) of your sd card and the boot partition (usually part2); mount proc and sys of the "host" too (ie):
mount /dev/sdX4 /mnt mount /dev/sdX2 /mount/boot mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys
then chroot /mnt
You may need to copy the /etc/resolve.conf from your host system to kickstart networking.
_OT_ For personal use and on request from others I made a flash-able img file with 4.18.16 installed. It is a bit different from the default userland-generic though: 2 partitions starting @4096 (1) boot (2) rootfs; compressed swap-space in ram. NOTE: this link may be short lived as the setup is experimental https://drive.google.com/open?id=1PvLxWVwvK9H2zJTnBF2rKlA7IDmbpa7s and my rough notes on the HC1: https://gist.github.com/markVnl/7adf25cebfdce5d5009d93b7b4caae96 _OT_
