Introduce SYNAPTICS_SL2619, which selects ARM64, along with ARCH_SYNAPTICS
which selects driver model, SYS_NS16550 and GIC-v2.

Use "N: synaptics" instead to cover most of these.
Ok.

Isn't this allowed upstream?
Definitely.
Jisheng, maybe you could add it in the DTS in your v2?

Shouldn't this be with the ARCH symbol? Or are there 32bit cores you'll
be supporting later?
Indeed, I think it's safe to say that there will be only 64bits.
I'll change that
Otherwise seems quite reasonable and I'm glad to see this posted,
thanks!
Great!
Thanks!

Richard
