TI is also planning to implement the same in our upcoming platform. so
can we use a generic ID instead of vender specfic message ID?

I tried to push to new generic ID [1] in half a year ago, but in the end ARM
decided not to add generic ID for spread spectrum support.

To i.MX, it is too late to use a generic ID and waiting spec, i.MX firmware
has been public for quite some time and passed several external releases.
So I need to use what our firmware adds and spec allows: vendor
extension.
