fbada4855d net: fec: sharing MDIO for two enet controllers
On i.MX6SX, 6UL and 7D, there are two enet controllers each has a
MDIO port. But Some boards share one MDIO port for the two enets. So
introduce a configuration CONFIG_FEC_MXC_MDIO_BASE to indicate
the MDIO port for sharing.
In Kconfig, user needs enable CONFIG_FEC_MXC_SHARE_MDIO first to enter
the CONFIG_FEC_MXC_MDIO_BASE.

To i.MX28, adapt to use the new config

To platforms has two enet interface, using dev->seq could
avoid conflict.

i.MX6UL/ULL evk board net get the wrong MAC address from fuse,

07763ac928 net: fec_mxc: Fix DM driver issue in recv
When using ethernet DM driver, the recv interface has a
change with non-DM interface, that driver needs to set
the packet pointer and provide it to upper layer to process.

In fec driver, the fecmxc_recv functions does not handle the
packet pointer parameter. This may cause crash in upper layer
processing because the packet pointer is not set.

This patch allocates a buffer for the packet pointer and free it
through free_pkt interface.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

"A receive FIFO overrun can be expected if network packages are not

With the network patches we check if a package is available quite often."

Move the "error frame" messages to debug level so that a clean output

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.

f599288d55 net: fec_mxc: Poll FEC_TBD_READY after polling TDAR
When testing the FEC driver on a mx6solox we noticed that the TDAR bit gets
always cleared prior then the READY bit is cleared in the last BD, which causes
FEC packets reception to always fail.

As explained by Ye Li:

"The TDAR bit is cleared when the descriptors are all out from TX ring, but on
mx6solox we noticed that the READY bit is still not cleared right after TDAR.
These are two distinct signals, and in IC simulation, we found that TDAR always
gets cleared prior than the READY bit of last BD becomes cleared.
In mx6solox, we use a later version of FEC IP. It looks like that this
intrinsic behaviour of TDAR bit has changed in this newer FEC version."

Fix this by polling the READY bit of BD after the TDAR polling, which covers the
mx6solox case and does not harm the other SoCs.

No performance drop has been noticed with this patch applied when testing TFTP
transfers on several boards of different i.mx SoCs.

db5b7f566e net: fec_mxc: Adjust RX DMA alignment for mx6solox
mx6solox has a requirement for 64 bytes alignment for RX DMA transfer.
Other SoCs work with the standard 32 bytes alignment.

Adjust it accordingly by using 64 bytes aligment in the FEC RX DMA buffers,
which addresses the needs from mx6solox and also works for the other SoCs.

fd37f195ca net: fec_mxc: Fix timeouts during tftp transfer
Performing tftp transfers on mx28 results in random timeouts.

Hector Palacios and Robert Hodaszi analyzed the root cause being related to the
wrong alignment of the 'buff' buffer inside fec_recv().

Benoît Thébaudeau provided an excellent analysis of the alignment bug that is
present on older versions, such as GCC 4.5.4:

http://marc.info/?l=u-boot&m=137942904906131&w=2

Use ALLOC_CACHE_ALIGN_BUFFER() to avoid alignment issues from older GCC
versions.

ab94cd491f net: fec: Avoid MX28 bus sync issue
The MX28 multi-layer AHB bus can be too slow and trigger the
FEC DMA too early, before all the data hit the DRAM. This patch
ensures the data are written in the RAM before the DMA starts.
Please see the comment in the patch for full details.

This patch was produced with an amazing help from Albert Aribaud,
who pointed out it can possibly be such a bus synchronisation
issue.

67449098a8 FEC: Rework the TX wait mechanism
The mechanism waiting for transmission to finish in fec_send() now
relies on the E-bit being cleared in the TX buffer descriptor. In
case of data cache being on, this means invalidation of data cache
above this TX buffer descriptor on each test for the E-bit being
cleared.

Apparently, there is another way to check if the transmission did
complete. This is by checking the TDAR bit in the X_DES_ACTIVE
register. Reading a register does not need any data cache invalidation,
which is beneficial.

Rework the sequence that wait for completion of the transmission so that
the TDAR bit is tested first and afterwards check the E-bit being clear.
This cuts down the number of cache invalidation calls to one.

9d2d924a0a net: fec_mxc: Fix setting of RCR for xMII
At least on i.MX25, the RMII mode did not work, which is fixed by this patch.

The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.

According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

To use multiple controllers, new macro is in place, the mxcfec_register_multi(),
which takes more arguments. The syntax is:

mxcfec_register_multi(bd, FEC ID, FEC PHY ID on the MII bus, base address);

To disable the fecmxc_register() compatibility stuff, define the macro
CONFIG_FEC_MXC_MULTI. This will remove the requirement for defining IMX_FEC_BASE
and CONFIG_FEC_MXC_PHYADDR.

f699fe1e1f net,fec: Shorten device name as done for other drivers
After discussion on the ML it is suggested to drop unrequired
and not useful characters from the device name.
This patch changes the name for the fec_mxc driver from
"FEC_MXC" to "FEC".

c179a2896e fec_mxc: incomplete error handling
fec_init() will only allocate fec->base_ptr if it is non-NULL. But
the cleanup routine on error will free the pointer without setting
it to NULL. This means that a later call to fec_init() would result
in using an invalid pointer.

651ef90fa6 mxc_fec: avoid free() calls to already freed pointers.
Sometimes, inside NetLoop, eth_halt() is called before eth_init() has
been called. This is harmless except for free() calls to pointers
which have not been allocated yet.

This patch initializes those pointers to NULL and allocates them only
the first time. This way we can get rid of free calls in halt callback.

This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.
