Hi all,
This patch series adds support for the Broadcom BCM53xx switches, in particular BCM53125 which is found no the Lamobo R1 board.
The driver is largely based on the DSA/b53 driver Linux driver and only incorporates what is necessary to succesfully bring-up all ports (including the management port) for boot over the network:
=> dhcp dw_adjust_link: Speed: 1000, full duplex BOOTP broadcast 1 DHCP client bound to address 192.168.0.11 (3 ms) Using ethernet@01c50000 device TFTP from server 192.168.0.1; our IP address is 192.168.0.11 Filename 'sun7i-a20-lamobo-r1-kernel.bin'.

Joe there is one warning left which does not look legit to me since we now have a help paragraph describing the config symbol:
WARNING: please write a paragraph that describes the config symbol fully #34: FILE: drivers/net/phy/Kconfig:15: +config B53_SWITCH
and one CHECK left which I intentionally did not fix because it makes the definitions of the bits less clear: CHECK: Prefer using the BIT macro #134: FILE: drivers/net/phy/b53.c:63: +#define PORT_OVERRIDE_SPEED_100M (1 << PORT_OVERRIDE_SPEED_S)
Changes in v4: - address most checkpatch.pl issues, couple remaining, one which looks bogus:
Changes in v3: - dropped redundant phydev->priv assignment in b53_probe(), spotted by Joe
Changes in v2:
- collected Sefan's Reviewed-by and Joe's Acked-by tags - use max() in drivers/net/designware.c as suggested by Joe
