Hi Marty,
Does this confict with your patch? If not,I hope this could be merged first.  Besides could you tell me the link to your related patch?
This is the link: https://patchwork.kernel.org/patch/9334743/
Thank you for offering this.If I want to give some comments on Marty's patch,
what should I do?

For Marty's patch, I think there's no need to add specific config item ARCH_HIxxxx
for every chipset. Some existing chipsets depend on ARCH_HISI directly like Hi3519
and Hi3798CV200. If some options like ARM_GIC is removed from ARCH_HISI, this kind
of chipsets will must choose other place to select it. I suggest we should keep selecting
ARM_GIC under ARCH_HISI as Pan's patch do.

The code may be like this:

config ARCH_HISI
 	bool "Hisilicon SoC Support"
-	depends on ARCH_MULTI_V7
+	depends on ARCH_MULTI_V5 || ARCH_MULTI_V6 || ARCH_MULTI_V7
 	select ARM_AMBA
-	select ARM_GIC
+	select ARM_GIC if ARCH_MULTI_V7
+	select ARM_VIC if ARCH_MULTI_V5 || depends on ARCH_MULTI_V6
 	select ARM_TIMER_SP804
 	select POWER_RESET
 	select POWER_RESET_HISI
 	select POWER_SUPPLY

What's your opinion?

Best Regards,
Jiancheng

Add support for some HiSilicon SoCs which depend on ARCH_MULTI_V5.

Looks ok. I've added Marty Plummer to Cc, he was recently proposing
patches for Hi3520, which I think is closely related to this one.
Please try to work together so the patches don't conflict. It should
be fairly straightforward since you are basically doing the same
change here.
