This series improves the Pine64 support. The first patch fixes a build break, see details in the commit message. Patch 2/6 reverts a no longer needed memory reservation, as the firmware bits that used to live in DRAM now can reside in SRAM. To allow U-Boot to be easily loaded by Allwinner's boot0 loader, patch 3/6 reserves some space at the beginning of the image to (optionally) fit in a header required by boot0. Patch 4/6 adjusts the default load addresses in the environment to meet the arm64 requirements (especially the kernel load address). The device tree files included in the original Pine64 commit are outdated, so patch 5/6 replaces some with more mature versions and also adjusts the naming to match other sunxi boards. The final patch renames the _defconfig file to get rid of the _plus_ insert.
Please review, comment and apply, if possible.
Cheers, Andre.
P.S. tools/buildman/README was TL;DR, so I just tested Pine64 and Bananapi compilation. If someone with a working buildman setup could test this for build regressions, I'd be grateful.
