The HiSillicon Hi3519 V100 is based on ARM but not standard arm, it does use the Cortex-A53 CPU. Possible / hard to add suport for this arch?

It does seem to have fairly wide use.

What would have to change in Go in order to add support for this?

Go generally doesn't care about anything other than the CPU, so if it uses a standard ARM CPU what is there to do?

That is what I thought. Hisilicon has their own modifications to Standar Library, Linux Kernel, cross compile toolchain, not sure what else, this matters not for GO?

Changes to the standard library and cross-compiler toolchain are almost certainly irrelevant to Go. Changes to the kernel could possibly matter, but only if they changed the system call interface which is extremely unlikely. So I doubt we need to do anything. Of course please let us know if you find out otherwise.
