[Sound-open-firmware] Timer implementation: Haswell vs Baytrail

[Daniel Baluta]

Hi all,

Can someone explain what is the difference between
hsw vs byt timer implementation?

It looks like hsw uses a generic xtensa timer
implementation based on directly reading Xtensa
special registers while Byt uses some bits in SHIM layer.

What is the advantage of byt implementation?

Also, the implementation for hsw looks generic enough
so that it can be used by other architectures that do
not have a shim layer, right?

thanks,
Daniel
