The most important is probably regression fix in handling platform
NVRAM. That bug stopped hardware from being properly calibrated breaking
e.g. 5 GHz for Netgear R8000.
Other than that it triggers memory dumps when experiencing firmware
problems which is important for debugging purposes.

Subject: [PATCH] brcmfmac: trigger memory dump upon firmware halt signal
|
|
|
|
PCIe dongle firmware signals a halt/trap through mailbox interrupt.
|
|
Trigger a memory dump upon receiving such signal could help to provide
|
|
useful information for issue debug.
