Cédric Le Goater May 19, 2020, 4:19 p.m. UTC
The AST2400 and AST2500 SoCs have two MACs but only the first MAC0 is
active on the Aspeed machines using these SoCs. The AST2600 has four
MACs. The AST2600 EVB machine activates MAC1, MAC2 and MAC3 and the
Tacoma BMC machine activates MAC2.

Introduce a bit-field property "macs-mask" under the Aspeed SoC model
to link the active MACs of the machine being started with the available
network devices.

Inactive MACs will have no peer and QEMU will warn the user with :

    qemu-system-arm: warning: nic ftgmac100.0 has no peer
    qemu-system-arm: warning: nic ftgmac100.1 has no peer
    qemu-system-arm: warning: nic ftgmac100.3 has no peer
