[U-Boot] [PATCH v4 0/4] net: phy: Add Broadcom BCM53xx switch driver

[Florian Fainelli]

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 at 01c50000 device
TFTP from server 192.168.0.1; our IP address is 192.168.0.11
Filename 'sun7i-a20-lamobo-r1-kernel.bin'.
Load address: 0x42000000

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
