Add new driver for the TI AM65x SoC Gigabit Ethernet Switch subsystem
(CPSW
NUSS). It has two ports and provides Ethernet packet communication
for the
device and can be configured as an Ethernet switch. CPSW NUSS
features: the
Reduced Gigabit Media Independent Interface (RGMII), Reduced Media
Independent Interface (RMII), and the Management Data Input/Output
(MDIO)
interface for physical layer device (PHY) management. The TI AM65x
SoC has
integrated two-port Gigabit Ethernet Switch subsystem into device MCU
domain named MCU_CPSW0. One Ethernet port (port 1) with selectable RGMII
and RMII interfaces and an internal Communications Port Programming
Interface (CPPI) port (Host port 0).
Host Port 0 CPPI Packet Streaming Interface interface supports 8 TX
channels and on RX channels operating by TI am654 NAVSS Unified DMA
Peripheral Root Complex (UDMA-P) controller.
Tested for tftp and booting to kernel on am654-evm.

Needs to be applied before trying the cpsw.
Tom,
Thanks for pulling this series and as pointed above please pull the
patch [1] which will avoid udma accessing RT registers before channel
config is done.
Tom,
I do not see this series in latest u-boot. Was this dropped for some reason?

Changes in v4:
* Patch1 caused dra7 config build warnings corrected them.
Testing:
1) Build tested am3/4 and dra7.
2) Booted to kernel using cpsw tftp.
