Now that the armvirt target supports real hardware, not just VMs, thanks to the addition of EFI, rename it to something more appropriate. 'armsr' (Arm SystemReady) was chosen after the name of the Arm standards program. The 32 and 64 bit targets have also been renamed armv7 and armv8 respectively, to allow future profiles where required (such as armv9). See https://developer.arm.com/documentation/102858/0100/Introduction for more information. Signed-off-by: Mathew McBride <matt@traverse.com.au>

Subject: [PATCH 08/14] net: dpaa2-switch: assign port_priv->mac after
|
|
dpaa2_mac_connect() call
|
|
|
|
The dpaa2-switch has the exact same locking requirements when connected
|
|
to a DPMAC, so it needs port_priv->mac to always point either to NULL,
|
|
or to a DPMAC with a fully initialized phylink instance.
|
|
|
|
Make the same preparatory change in the dpaa2-switch driver as in the
|
|
dpaa2-eth one.
