[U-Boot] [PATCH 00/12] sunxi: Allwinner H5 and OrangePi PC2 support

> This series introduces support for the Allwinner H5 SoC with four
> Cortex-A53 cores. The SoC's peripherals are very similar to the H3,
> although the cores and the BROM/SRAM layout resembles the A64.
> The first 6 patches contain some fixes and refactoring, to make code
> sharing between the three mentioned SoCs easier.
> Patch 07/12 adds support for the H5 DRAM controller, by extending
> the already existing combined H3/A64 DRAM code.
> Patch 08/12 renames the existing CONFIG_MACH_SUN8I_H3 config symbol to
> let it be used by all peripheral code that can be shared between the
> H3 and H5. Patch 10/12 introduces the H5 SoC config option into Kconfig,
> which defines this shared symbol as well.
> Patch 11/12 adds an easy device tree, which actually uses the H3 .dtsi
> and overwrites nodes which are different. This is good enough for U-Boot,
> the DT will be changed anyway once we get the DT merged into the Linux
> kernel.
> The final patch then adds the defconfig for the OrangePi PC2 board.
> Since this board comes with soldered SPI flash, we enable support for
> it in the SPL. This has been tested by writing the SPI flash with some
> special sunxi-fel version. The BROM loaded and executed the SPL, which
> in turn loaded and executed U-Boot proper. Both parts are 64-bit only
> for now.
> Ethernet support is enabled, but fails at the moment since the EMAC
> driver does not support setting a GPIO to enable the external Gigabit PHY.
> This should be a problem for H3 boards with Gigabit as well.
>
> At the moment this build suffers from the same problem as the A64: the
> ATF is missing, so Linux won't boot easily. However I finally managed to
> clean up the FIT extension series, which solves this problem in a quite
> elegant way. I will post this series after getting some sleep ;-)
>
> This series is on top of sunxi/next, which has three yet unmerged (and
> unrelated) patches compared to HEAD. So it should apply to both branches.
>
> Some of these patches will probably conflict with ongoing work from
> Icenowy, I am happy to rebase on any branch someone points me to.

No. It's me who should do rebase, as I have not done everything ;-)
