c59ab0921f CACHE: net: asix: Fix asix driver to work with data cache on
The asix driver did not align buffers, therefore it didn't work
with data cache enabled. Fix this.

6e5b9ac097 phylib: phy_startup() should return an error code on failure
phy_startup() calls the PHY driver's startup function, but it ignores the
return code from that function, and so it never returns any failures.

fa86d1c0bf mxs-i2c: Fix internal address byte order
Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory.
These devices require that the high byte of the internal address has to be
written first.
The mxs_i2c driver currently writes the address' low byte first.

The following patch fixes the byte order of the internal address that should
be written to the I2C device.

9ca37d78a3 mxc_i2c: remove setting speed at each start
Other then being very weird, this code was also wrong.
For example, say I set speed to 100K. I'll read back the speed
as 85937. But the speed is really 85937.5, so we I reset
the speed to 85937, I'll get 73660.7. After a couple of transactions
my speed is now exactly 68750 so it will remain there.

i2c_probe() is changed to reinit the i2c bus upon read failure.

Also, some printf messages upon read failure are removed. As they

Additionally, i2c_set_bus_speed() now returns 0, so that the
"i2c speed" command can be used.

ef76025a99 net: Multiple updates/enhancements to designware.c
This patch adds the following changes to designware ethernet driver
found on the ST SPEAr SoC:

- Don't init MAC & PHY upon startup. This causes a delay, waiting for
  the auto negotiation to complete. And we don't want this delay to
  always happen. Especially not on platforms where ethernet is not
  used at all (e.g. booting via flash).
  Instead postpone the MAC / PHY configuration to the stage, where
  ethernet is first used.
- Add possibility for board specific PHY init code. This is needed
  for example on the X600 board, where the Vitesse PHY needs to be
  configured for GMII mode.
  This board specific PHY init is done via the function
  designware_board_phy_init(). And this driver now adds a weak default
  which can be overridden by board code.
- Use common functions miiphy_speed() & miiphy_duplex() to read
  link status from PHY.
- Print status and progress of auto negotiation.
- Print link status (speed, dupex) upon first usage.

168a5acb81 Revert "I2C: OMAP: detect more devices when probing an i2c bus"
This reverts commit 0e57968a21.

The short version of the original commit is that some i2c devices cannot
be probed via read as they NAK the first cycle, so try and probe via a
write that we abort before it writes to the device.  This however is not
allowed by the TRM for any of these parts.  The section on I2C_CON
(table 17-35 I2C_CON for am/dm37x for example) says you must not change
the register while STT has been set.  On these parts, the unpredictable
behavior that the chip exhibits is not problematic.  On OMAP4 however it
results in the chip being in a bad state:
Panda # i2c probe

Panda # i2c md 50 0
timed out in wait_for_pin: I2C_STAT=0
I2C read: I/O error

We must revert the original behavior to bring probe back into line with
the TRM.

bccbe619b1 drivers/net/eepro100.c: Fix compile warning
Fix this:
eepro100.c: In function 'eepro100_initialize':
eepro100.c:464:13: warning: assignment from incompatible pointer type
eepro100.c: In function 'eepro100_recv':
eepro100.c:694:4: warning: passing argument 1 of 'NetReceive' discards qualifiers from pointer target type
include/net.h:438:13: note: expected 'uchar *' but argument is of type 'volatile u8 *'

The use of a descriptor like this may mean DMA will update this at will
Beware this may be a source of trouble on some boards
