Hi Andre,

A minor update to the v3 version sent earlier this month. I reworked patch 09 to drop the direct MMC environment for 32-bit Allwinner boards as well and keep the current MMC offset. For now I also dropped the two patches changing (back) the MMC regulator. I still believe they are good to have and keep them as U-Boot specific .dtsi files in my tree, possibly posting them later again.
As the previous version, this combines the EMAC DT support update with an update of the full Linux kernel DTs for all H3, H5 and A64 boards.
Patch 01 leaves some hint in the README how to avoid the situation when overrunning U-Boot's image size on 64-bit boards. The old v2 EMAC DT update series is in patches 02-08, it prepares U-Boot's EMAC driver for using the new DT binding used in Linux, also updates the DTs to the new EMAC DT node already.
Changes to sync the whole of U-Boot's DT files for the H3, H5 and A64 SoCs to those from Linux are in the following patches. However this first requires lifting the space limit we currently have due to the raw MMC environment. Patch 09 disables that for all sunxi boards, to give us finally some space. Patches 10 and 11 consequently revert the disabling of features we saw a few weeks ago to migitate the size problem.
Patches 12-19 then bring in the Linux DTs, split by SoCs, with the .dtsi files first, then the board files.
Merging the H3 and H5 device tree files brings in significant changes, also to the structure of the .dtsi files. However U-Boot's own DT usage is pretty limited, so it doesn't matter.
The huge benefit of syncing the DTs is that we can use U-Boot's DT copy to directly pass it to the kernel, avoiding to actually load a .dtb file from somewhere. To allows seamless and automatic UEFI booting, so distribution installer images should just work (TM).
As a goodie the final patch brings in the actual SoPine + baseboard DT files, which we were completely missing so far.
This is based on sunxi/master (2d53018a0ef2).
Cheers, Andre.

Can you rebase and fix few checkpatch issue on these 11 patches?
