[PATCH v2 0/8] arm64: Add initial Actions Semi S700 and CubieBoard7 support

[PATCH v2 0/8] arm64: Add initial Actions Semi S700 and CubieBoard7 support

[Andreas Färber]

Hello,

This series prepares the Actions Semi S700 SoC and Cubietech CubieBoard7.
It boots equally far as the S900 based Bubblegum-96 these patches are based on,
i.e. into an initrd with serial and all four cores up.

v2 modifies the clocksource driver patches and adds SPS patches.

Not having succeeded to replace the bootloader on eMMC or to try
booting from SD, the only working way I've found to boot mainline kernels
appears to be booting into Android, then issuing "reboot bootloader". U-Boot
is lacking the saveenv command, so it wasn't possible to change the bootdelay
to facilitate this.

Cf. https://en.opensuse.org/HCL:CubieBoard7

Work branch:
https://github.com/afaerber/linux/commits/bg96-next

Have a lot of fun!

Cheers,
Andreas

v1 -> v2:
* Prepended patch converting CLOCKSOURCE_OF_DECLARE() to TIMER_OF_DECLARE() (Daniel)
* Added patches for SPS

Are you planning to queue this v2 patch for 4.16?

In linux-next already.

If you take 2-4, I can take 5; if you'd rather have me take the binding,
fine with me as well.

Yeah, but that does not mean the patch is merged. Do you mean it is
merged in arm-soc, so it is visible in linux-next?

I will take patches 2-4.

No, I am waiting to send my initial 4.16 pull to arm-soc and wanted to
clarify what (if anything) from this series can still go into that pull.

Is it possible this change fixes your issue ?

Actions is not yet supported in mainline U-Boot, and S500 boards did not
have a problem there. The saveenv command is simply not enabled in this
config deployed by Cubietech. Since I have not succeeded in getting a
self-built U-Boot booted from SD, I cannot test individual commits on
top either.

Maybe Cubietech or Actions can comment?

Andreas
