Hi Clément,

The Eachlink H6 Mini is a modestly priced TV box, using the Allwinner H6 SoC. It comes with 4GB of DRAM (3GB usable) and 32GB of eMMC in the typical TV box enclosure. This adds a basic device tree and defconfig for it.
It contrast to the other supported H6 boards the H6 Mini uses DDR3 DRAM chips (not LPDDR3), which require a different DRAM controller setup.

Same as Pine H64. If you plan to mainline this board in Linux maybe you should try to stuck with the linux one to avoid any differences.
Well, there is no DT in Linux yet, so how could I deviate? In fact I will send an ideally identical .dts to Linux later this week, so we have this bit in from the beginning.
I think it's a bit of a chicken and egg problem: I can't really post Linux support patches without having U-Boot running, so have to start somewhere.

This is now the default and it's no more required.
I know, but it's not in current mainline, which this patch is against.

You should also add yourself in the MAINTAINERS file for the dts and config file of the board.
Sure.
Thanks for having a look!
Cheers, Andre.
