a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

9c9141fd04 net: tsec: Use portable types and accessors for BDs
Currently, the buffer descriptor (BD) fields cannot be
correctly accessed by a little endian processor.  This
patch fixes the issue by making the access of BDs to be
portable among different cpu architectures.

Use portable data types for the Rx/Tx buffer descriptor
fields.  Use portable I/O accessors to insure that the
big endian BDs are correctly accessed by little endian
cpus too, and to insure proper sync with the H/W.
Removed the redundant RTXBD "volatile" type, as proper
synchronization around BD data accesses is provided by
the I/O accessors now.
The "sparse" tool was also used to verify the correctness
of these changes.

Remove tsec_t typedef.  Define macros as getters of

Use the __iomem address space marker to address sparse

tsec.c:394:19: warning: incorrect type in argument 1 (different
address spaces)
tsec.c:394:19:    expected unsigned int volatile [noderef]
<asn:2>*addr
tsec.c:394:19:    got unsigned int *<noident>
[...]

to struct tsec_mii_mng memory mapped register regions.
This solves the sparse warnings for mixig normal pointers
with __iomem pointers for tsec.

b200204e8e net: tsec: Fix priv pointer in tsec_mcast_addr()
Access to privlist[1] (hardcoded referece to the 2nd tsec's
priv area) is neither correct nor does it make sense in the
current context.  Each tsec dev has access to its own priv
instance only, and hence to its own set of group address
registers (GADDR) to filter multicast addresses.

This fix leads to removal of the unused (faulty) privlist[]
and related global static vars.  Note that mcast() can be
called only after eth_device allocation and init, and hence
after priv area allocation, so dev->priv is correctly
initialized upon mcast() call.

    tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode

Removed setting Auto-Neg by default, however this is believed to be
proper default configuration for initialization of the TBI interface.

Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the
XPedite5370 & XPedite5500 boards that use a Broadcomm PHY which require
Auto-Neg to be disabled to function properly.

This addresses a breakage on the P2020 DS & MPC8572 DS boards when used
with an SGMII riser card.  We also remove setting
CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the
default setting is sufficient for them.

Additionally, we clean up the code a bit to remove an unnecessary second
define.

daa2ce6292 tsec: fix the return value for tsec_eth_init()
The Ethernet initialization functions are supposed to return the number of
devices initialized, so fix tsec_eth_init() so that they returns the number of
TSECs initialized, instead of just zero.  This is safe because the return value
is currently ignored by all callers, but now they don't have to ignore it.

In general, if an function initializes only one device, then it should return
a negative number if there's an error.  If it initializes more than one device,
then it should never return a negative number.

46e91674fb tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode
In SGMII mode the link between a processor's internal TBI PHY and an
external PHY should always be 1000Mbps, full duplex.  Also, the SGMII
interface between an internal TBI PHY and external PHY does not
support in-band auto-negotation.

Previously, when configured for SGMII mode a TBI PHY would attempt to
restart auto-negotation during initializtion.  This auto-negotation
between a TBI PHY and external PHY would fail and result in unusable
ethernet operation.

Forcing the TBI PHY and and external PHY to link at 1000Mbps full duplex
in SGMII mode resolves this issue of auto-negotation failing.

Note that 10Mbps and 100Mbps operation is still possible on the external
side of the external PHY even when SGMII is operating at 1000Mbps.
The SGMII interface still operates at 1000Mbps, but each byte of data
is repeated 100 or 10 times for 10/100Mbps and the external PHY handles
converting this data stream into proper 10/100Mbps signalling.

b9e186fc31 NET: Move MDIO regs out of TSEC Space
Moved the mdio regs out of the tsec structure,and
provided different offsets for tsec base and mdio
base so that provision for etsec2.0 can be provided.

This patch helps in providing the support for etsec2.0
In etsec2.0, the MDIO register space and the etsec reg
space are different.

Also, moved the TSEC_BASE_ADDR and MDIO_BASE_ADDR definitons into
platform specific files.

0d071cdd78 net: tsec - handle user interrupt while waiting for PHY auto negotiation to complete
if you don't have firmware installed for the PHY to come to life, this
wait can be painful - let's give the option to avoid it if we want.

b1e849f220 tsec: Wait for auto-negotiation to complete without link
Previously, waiting for auto-negotiation would only occur if a valid
link had been detected.  Problems arose when attempting to use a
tsec immediately after bootup but before link was achieved, eg:
=> dhcp
Auto-neg error, defaulting to 10BT/HD
eTSEC1: No link.
Auto-neg error, defaulting to 10BT/HD
eTSEC2: No link.
=>

With this patch applied the same operation as above resulted in:
=> dhcp
Waiting for PHY auto negotiation to complete. done
Enet starting in 1000BT/FD
Speed: 1000, full duplex
