Hot plug support for aspeed-smc driver

[Shakeeb B K]

Hi All,

We have a use case for dynamic enabling/disabling access to spi nor flash
using an external mux.
This is mainly for data flash access over spi controller.

Since we use aspeed-smc driver for both fmc and smc, we cannot make it
loadable as of now.
Is there any way to handle this other than writing a new implementation for
spi controller?

Thanks,
Shakeeb
