On some boards using TI CPSW, it may be possible that
PHY address was not latched correctly, and the actual
address that the phy responds on is different from that
set in device-tree. For example, see this problem report
on beaglebone black:
https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J
Add support to check for this condition and use the
detected phy address when its safe to do so.
Also, add a public API that exposes the phy address of
a given slave. This can be used to update device-tree that
is passed to Linux kernel.

cpsw driver supports only selection of phy mode in control module
but control module has more setting like RGMII ID mode selection,
RMII clock source selection. So ported to cpsw-phy-sel driver
from kernel to u-boot.

Add the ability to read the phy-handle node of the
cpsw slave. Upon reading this handle the phy-id
can be stored based on the reg node in the DT.
The phy-handle also needs to be stored and passed
to the phy to access any phy data that is available.

Different TI platforms has to read with different combination to
get the mac address from efuse. So add support to read mac address
based on machine/device compatibles.
The code is taken from Linux drivers/net/ethernet/ti/cpsw-common.c
done by Tony Lindgren.

Some platforms like AM437x have different EVMs with different phy addresses,
so this patch adds support for passing phy address via cpsw plaform data.
Also renamed phy_id to phy_addr so better understanding of the code.

CPSW is an on-chip ethernet switch that is found on various SoCs from Texas
Instruments. This patch adds a simple driver (based on the Linux driver) for
this hardware module.
This patch also adds support to clean and flush dcache during packet send
and receive.
Changes by Sandhya: Added support to clean and flush dcache during packet
send/receive and added timeouts.
