Subject: [PATCH 4/6] MIPS: BCM63XX: provide a MAC address for BCM3368 chips
|
||
|
|
|
||
|
|
The BCM3368 SoC uses a NVRAM format which is not compatible with the one
|
||
|
|
used by CFE, provide a default MAC address which is suitable for use and
|
||
|
|
which is the default one also being used by the bootloader on these
|
||
|
|
chips.
