This adds Cubieboard7[1] support based on Action Semi's S700 SoC[2], It's Quad-core ARMv8 SoC with Cortex-A53 cores. Peripheral like UART seems to be compatible with S900 SoC(basic support for it is alreay present in u-boot).
This series(v10) takes care the commments provided by Mani and patches 04/12, 07/12 and 12/12 has been changed to address those comments.
Previous series(v9) fixes a Bug that breaks bubblegum96 board boot(reported by Mani). It was due to fact that driver data read is not proper in the clock driver. There are changes in patch 06/12 to fix it.
Series(v8) removes the SoC specific include instead just uses owl-common. For this patch 01/12 and 09/12 changes a bit.
Series(v7) fixes a serious Bug that breaks S900, it was there since v5.Thanks to Andre for pointing it out.
Series(v6)[3] does following changes:
- [PATCH v5 06/11] becomes [PATCH v6 03/11]
- [PATCH v5 03/11] becomes [PATCH v6 04/11]
- Introduce a new patch to move defconfig options to Kconfig which is [PATCH v6 10/12]
Series(v5)[4] just re-orders the patches so that U-BOOT(with bubblegum96_defconfig) builds after every patch of the series(suggested by Andre).
S700 support is tested[5] on Cubieboard7-lite board and S900 support is just compiled tested.
This patch series can be tested using below tree: https://github.com/Atomar25/u-boot/commits/s700_v10

A few problems. First, "actions: Move defconfig options to Kconfig" breaks a large number of boards including p2371-2180 in one way and libretech_all_h5_cc_h5 (along with lots of other sunxi platforms) in a different but related way.
(Masahiro: it's about this patch: https://lists.denx.de/pipermail/u-boot/2020-April/405672.html)
Tom, many thanks for the heads up, I can confirm the problem, but am totally clueless as of *why* this happens: The changes in this patch add options to arch/arm/mach-owl/Kconfig, and are totally contained inside an "if ARCH_OWL .. endif" clamp, so how could this even affect other platforms (which are clearly not defining ARCH_OWL)?
Cheers, Andre
Second, the new defconfig isn't listed under any MAINTAINERS file and needs to be. I had fixed this up while testing but the other problem is more severe and needs looking in to. Thanks!
