0229c9330d board: ti: am335x: Add platdata for cpsw in SPL
The SPL image overflows when cpsw dt nodes are added and SPL_OF_CONTROL
is enabled. Use static platdata instead to save space.

a58d222df9 net: ti: cpsw-common: Isolate getting syscon address from assigning macid
ti_cm_get_macid() is used to get a syscon node from the dt, read the
efuse address and then assign the macid read from the address. Divide
these two steps into separate functions one of which can be called from
ofdata_to_platdata() while the other can be called from _probe(). This
ensures that platdata can be assigned statically in a board file when
OF_CONTROL is not enabled. Also add a macid_sel_compat in private data
to get information about the macid byte placement.

e50f878c98 net: ti: cpsw: Move cpsw_phy_sel() to _probe()
cpsw_phy_sel() is a configuration step that should not be in
ofdata_to_platdata(). Add phy_sel_compat to the cpsw_platform_data
structure so that it is accessible in _probe. Then move the call of
cpsw_phy_sel() to _probe.

e2597be5bc drivers: net: cpsw: add support to update phy address
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.

ab9715303d driver: net: cpsw: add support for RGMII id mode support and RMII clock source selection
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.

cb3862277b drivers: net: cpsw: Add reading of DT phy-handle node
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.

e4310566de drivers: net: cpsw: add support for reading mac address from efuse
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.

9c653aad16 drivers: net: cpsw: add support to have phy address from cpsw platform data
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.
