[v4] riscv: Add support for MIPS P8700 CPU

[PATCH v4 11/11] riscv/boston-aia: Add an e1000e NIC in slot 0 func 1

Posted by Djordje Todorovic 4 months, 3 weeks ago

The Boston AIA board needs a basic GbE NIC.  There is no PCH GbE
device emulation, so use an `e1000e` instead.  We place it in
**slot 0, function 1** in order not to conflict with the existing
AHCI device in slot 0 func 0.
