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 ;-)
Please have a look and let me know your opinion!
Cheers, Andre.
