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(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.
Previous 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 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_v9
Many thanks for your patience and continuous effort! I have now reviewed the series. Mostly is looks very good now. I just had few nit picks which you can address in v10.
This series won't make it for v2020.04 but that's not critical IMO.
Andre, thanks to you too for helping with the reviews. Much appreciated!
Thanks, Mani
