I got it working back then, but since then I have lost that U-Boot and
I'm now trying to bring this little box back to life using the U-Boot
mainline but without success.
Admittedly, it's not as simple because I can't just use the "fex" file
that came with the Android install and furthermore U-Boot has changed
a lot since then, the mini-x-a10s option got lost along the way, and I'm
a bit lost myself.
I tried to create some `foo_defconfig` and `foo.dts` files inspired from
the a10s-olinuxino and r7-tv-dongle ones, but that's not giving me
anything (the led goes red when I put the power and that's that) and I'm
not really surprised, because I don't really know what I'm doing.
Could someone help me? I've appended my current diff against U-Boot's
`master`.
