Hi,
has anyone successfully set up Gentoo on an odroidH2 using an eMMC?
I have got as far as the pivot-root (so it loads and executes the
intramfs) but fails to find the /dev/mmcblk0p[01] devices. The sting
is I copied the files it to a USB key and that boots fine! It appears
that the eMMC initramfs is not loading the modules for the eMMC where
as the USB version is (and they are using the same file!). I have
tried manually loading the modules from the efi shell I think are
involved but no mmc devices appear.
The eMMC runs uefi from GPT partitions using refind but as the bios
finds and loads the ramdisk I think thats working ok (I did a working
ubuntu install first, then reused those partitions.) I can use usb
early boot to pivot to the root on the USB key but so far cant pivot
from the eMMC initramfs to real_root. Ubuntu uses grub, which I tried
first but had even less success with that.
Hints anyone?

One further point, I cant boot off the usb and pivotroot to the eMMC
root - again no eMMC modules loaded. But once the usb root is running,
the eMMC modules are loaded. Its looking like the kernel device
detection needs real root which is ... odd!
