Subject: [PATCH 0/2] Add support for Zyxel EX3510-B

Hello BCMBCA maintainers,

This pair of patches adds an initial DT for the Zyxel EX3510-B "series" based
on BCM4906, encompassing the EX3510-B0 and EX3510-B1. As I am not aware of any
software-affecting difference between these two, I am calling the "series" one
model.

I found the BCM4906/8 support in Linux to be in need of a lot of TLC, and have
just sent a few patches necessary to get Linux to boot without crashing on this
platform. At a minimum, you will want to apply [1] to resolve a panic related
to xHCI not initializing. If you are booting through CFE and want to use the
secondary CPU, you will have to apply [2] as well.

There are more patches to come. An issue with the switch driver is preventing
the WAN port from operating, for example. I have worked around this locally so
I can confirm that the DT I am submitting here is correct, but I will need to
clean up my remaining local fixes before they can be sent.

As always, thank you very much for your continued efforts and for your time
reviewing these patches.

Best regards,
Sam
