We may have found a bug in the nxp/lpc_eth.c driver. The function
platform_set_drvdata() is called twice, the second time it is called,
in lpc_mii_init(), it overwrites the struct net_device which should be
at pdev->dev->driver_data with pldat->mii_bus. When trying to remove
the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will
return the pldat->mii_bus pointer and try to use it as a struct
net_device pointer. This causes unregister_netdev to segfault and
generate a kernel BUG. Is this reproducible?

When connected to a micrel phy, phy_find_first doesn't work properly
because the first phy found is on address 0, the broadcast address but, the
first thing the phy driver is doing is disabling this broadcast address.
The phy is then available only on address 1 but the mdio driver doesn't
know about it.
Instead, register the mdio bus using of_mdiobus_register and try to find
the phy description in device tree before falling back to phy_find_first.
This ultimately also allows to describe the interrupt the phy is connected
to.

Semantic patch information:
This makes an effort to choose between !x and x == NULL. !x is used

Setting the phy mode requires touching a platform specific
register, which prevents us from building the driver without
its header files.
Move it into a separate function in arch/arm/mach/lpc32xx
to hide the core registers from the network driver.

The lpc_eth driver uses a platform specific method to find
the internal sram. This prevents building it on other machines.
Rework to only use one function call and keep the other platform
internals where they belong. Ideally this would look up the
sram location from DT, but as this is a rarely used driver,
I want to keep the modifications to a minimum.

This patch fixes following (similar) warning reported by kbuild test robot:
In function ‘memcpy’,
inlined from ‘smsc75xx_init_mac_address’ at drivers/net/usb/smsc75xx.c:778:3,
inlined from ‘smsc75xx_bind’ at drivers/net/usb/smsc75xx.c:1501:2:

drivers/net/usb/smsc75xx.c: In function ‘smsc75xx_bind’:
./include/linux/string.h:355:9: note: in a call to built-in function ‘__builtin_memcpy’
I've replaced the offending memcpy with ether_addr_copy, because I'm
100% sure, that of_get_mac_address can't return NULL as it returns valid
pointer or ERR_PTR encoded value, nothing else.
I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this
would make the warning disappear also, but it would be confusing to
check for impossible return value just to make a compiler happy.
I'm now changing all occurencies of memcpy to ether_addr_copy after the
of_get_mac_address call, as it's very likely, that we're going to get
similar reports from kbuild test robot in the future.

With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

If the driver is used on an ARM platform with SPARSE_IRQ defined,
semantics of NR_IRQS is different (minimal value of virtual irqs) and
by default it is set to 16, see arch/arm/include/asm/irq.h.
This value may be less than the actual number of virtual irqs, which
may break the driver initialization. The check removal allows to use
the driver on such a platform, and, if irq controller driver works
correctly, the check is not needed on legacy platforms.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

Use strlcpy where possible to ensure the string is \0 terminated.
Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN
and custom defines.
Use snprintf instead of sprint.
Remove unnecessary inits of ->fw_version
Remove unnecessary inits of drvinfo struct.

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.
Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

If ndo_validate_addr is set to the generic eth_validate_addr
function there is no point in calling is_valid_ether_addr
from driver ndo_open if ndo_open is not used elsewhere in
the driver.
With this change is_valid_ether_addr will be called from the
generic eth_validate_addr function. So there should be no change
in the actual behavior.
