Thanks.

Yeah, I thought about only sending 3/3 until after we had the basics of 
the RPi4 platform in, but didn't see it as that big a deal to just send 
this whole thing as a set, since it does make sense to have all the 
Broadcom RNG related change grouped.

In case this is your concern, it's always been my plan to only start 
sending PCIe/xHCI related patches until after we have some of the basic 
platform in, so you won't be seeing any new Pi4-only changes at this 
stage, without them also being part of a set that allows testing.

Regards,
