[U-Boot] [PATCH v3 00/13] sunxi: Allwinner H5 and OrangePi PC2 support

[Andre Przywara]

Hi,

some small changes as requested by reviewers (many thanks for that!)

Maxime, Jagan,
given I get some ACKs or RBs on the remaining patches, is this good
to go for 2017.03 still?

Cheers,
Andre.

--------------------------
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 8 patches contain some fixes and refactoring, to make code
sharing between the three mentioned SoCs easier.
Patch 09/13 adds support for the H5 DRAM controller, by extending
the already existing combined H3/A64 DRAM code.
Patch 10/13 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 11/13 introduces the H5 SoC config option into Kconfig,
which defines this shared symbol as well.
Patch 12/13 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.

At the moment this build suffers from the same problem as the A64: the
ATF is missing, so Linux won't boot easily. With the RFC version of the
SPL FIT extension series on the list, applied on top of this one this
should now be solved.

This series is on top of origin/master.

Please have a look and let me know your opinion!

Cheers,
Andre.
