dc116bd6c4 net/phy: Correct AR8021 phy_mask
There was wrong phy_mask for AR8021 device,
so the AR8021 can't be probed correctly.
Changed it from 0x4fffff to 0x4ffff0.

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.

ee456337c6 SMC91111: Fix compilation warnings
This patch fixes the following warning messages coming out of
'drivers/net/smc91111.h' when compiled for 'vexpress_aemv8a':

warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Currently this issue seems to surface when SMSC is compiled for 64-bit
ARMv8 platforms, so the change is protected under CONFIG_ARM64, so that
it doesn't break other existing platforms.

In addition this patch tries to fix some checkpatch errors and warnings
(others related to camel-casing and volatile usage will be addressed
by a later patch).

This fix has been tested on both ARMv8 foundation model v1 and v2.

These two conflicts arise from commit 0b2d3f20
("ARM: NET: Remove the IXP NPE ethernet driver") and are
resolved by deleting the drivers/net/npe/Makefile file

6825a95b0b kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

50b0df814b net/designware: make driver compatible with data cache
Up until now this driver only worked with data cache disabled.
To make it work with enabled data cache following changes were required:

 * Flush Tx/Rx buffer descriptors their modification
 * Invalidate Tx/Rx buffer descriptors before reading its values
 * Flush cache for data passed from CPU to GMAC
 * Invalidate cache for data passed from GMAC to CPU

92a190aaab net/designware - switch driver to phylib usage
With this change driver will benefit from existing phylib and thus
custom phy functionality implemented in the driver will go away:
 * Instantiation of the driver is now much shorter - 2 parameters
instead of 4.
 * Simplified phy management/functoinality in driver is replaced with
rich functionality of phylib.
 * Support of custom phy initialization is now done with existing
"board_phy_config".

Note that after this change some previously used config options
(driver-specific PHY configuration) will be obsolete and they are simply
substituted with similar options of phylib.

For example:
 * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
by default.
 * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
automatically the first discovered on MDIO bus phy will be used

I believe there's no need now in "doc/README.designware_eth" because
user only needs to instantiate the driver with "designware_initialize"
whose prototype exists in "include/netdev.h".

74cb708d58 net/designware: add explicit reset of {tx|rx}_currdescnum
Driver "init" function might be called multiple times.
On every "init" Tx/Rx buffer descriptors are initialized: "descs_init"
-> "{tx|rx}_descs_init".

In its turn those init functions set MAC's "{tx|rx}desclistaddr" to
point on the first buffer descriptor in the list.

So CPU to start operation from the first buffer descriptor as well after
every "init" we have to reset "{tx|rx}_currdescnum".

c583ee16cb net: dm9000: random mac address support
When an unprogrammed EEPROM is attached to a dm9000, the dm9000 will
come up with a invalid MAC address of ff:ff:ff:ff:ff:ff.  Add code that
gets enabled if CONFIG_RANDOM_MACADDR is enabled that generates a random
(and valid) locally administered MAC address that allows the system to
network boot until a real MAC address can be configured.

8712adfd05 drivers/net/e1000: Introduce CONFIG_E1000_NO_NVM
The e1000 driver expects to always have some kind of non-volatile memory
attached directly to the ethernet controller chip. This means that I would
have to add an additional separate flash chip to my custom board just to
store essentially the MAC address. Since I don't want to do that, this patch
introduces a new config option CONFIG_E1000_NO_NVM. If defined it disables
all accesses to the NVM. I have tested the patch with a 82574 controller.
