Andrei Warkentin, Samer El-Haj-Mahmoud, Jeremy Linton
This is a followup to Samer's v1 [0], and incorporates all the delta
changes posted for review over the past couple of days. This is a
roundup of all that work, and therefore supersedes it.
It provides an implementation of the SimpleNetworkProtocol for the
Raspberry Pi4's GENET network controller, in a way that adheres to the
UEFI driver model.
The original submission was provided by Jared, based on Jeremy's MAC
programming-only driver and the existing BSD driver for the GENET IP.
Cumulative changes and fixes as well as review feedback were provided
by all of the below.

I pushed a delta patch to the branch above that fixes this, but I will wait for other feedback before sending it out, or sending out a v3, whichever is more appropriate. ^ permalink raw reply [flat|nested] 13+ messages in thread
