Commit 114d7fc0 "e1000: Rewrite EEPROM checksum error to give more
information" failed to initialize the checksum variable which should
result in random results. Fix that.
Commit 2326a94d caused a ton of "unused variable 'x'" warnings.
Fix these. While we are at it, remove some bogus parens.

As a part of the manufacturing process for some of our custom hardware,
we are programming the EEPROMs attached to our Intel 82571EB controllers
from software using U-Boot and Linux.
This code provides several conditionally-compiled features to assist in
our manufacturing process:
CONFIG_CMD_E1000:
This is a basic "e1000" command which allows querying the controller
and (if other config options are set) performing EEPROM programming.
In particular, with CONFIG_E1000_SPI this allows you to display a
hex-dump of the EEPROM, copy to/from main memory, and verify/update
the software checksum.
CONFIG_E1000_SPI_GENERIC:
Build a generic SPI driver providing the standard U-Boot SPI driver
interface. This allows commands such as "sspi" to access the bus
attached to the E1000 controller. Additionally, some E1000 chipsets
can support user data in a reserved space in the E1000 EEPROM which
could be used for U-Boot environment storage.
CONFIG_E1000_SPI:
The core SPI access code used by the above interfaces.
For example, the following commands allow you to program the EEPROM from
a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled):
usb start
fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin
e1000 0 spi program $loadaddr 0 1024
e1000 0 spi checksum update
Please keep in mind that the Intel-provided .eep files are organized as
16-bit words. When converting them to binary form for programming you
must byteswap each 16-bit word so that it is in little-endian form.
This means that when reading and writing words to the SPI EEPROM, the
bit ordering for each word looks like this on the wire:
Time >>>
------------------------------------------------------------------
... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ...
------------------------------------------------------------------
(MSB is 15, LSB is 0).

A followup patch will be adding a configurable feature to enable
programming of E1000 EEPROMs from the command line or via the generic
U-Boot SPI interface.
In order for it to work it needs access to certain E1000-internal
functions, so export those in the e1000.h header file.

As an aide to debugging, we should print out the expected value of the
EEPROM checksum in addition to just saying that it is wrong.

By allocating the e1000 device structures much earlier, we can easily
generate better error messages and siginficantly clean things up.
The only user-visable change (aside from reworded error messages) is
that a detected e1000 device which fails to initialize due to software
or hardware error will still be allocated a device number.
As one example, consider a system with 2 e1000 PCI devices where the
first controller has a corrupted EEPROM. Using the old code the
second controller would be "e1000#0", while with this change it would be
"e1000#1".
This change should hopefully make such EEPROM errors much more
straightforward to handle correctly in boot scripts and the like.
It is also necessary for a followup patch which allows SPI programming
of an e1000 controller's EEPROM even if the checksum is invalid.

nic and hw structures are allocated via malloc i.e. return memory
is not zero initialized. Because of this few structure member like
"function pointers" are initialized with garbage values.
It may cause problem. for eg. during eth_initialize, dev->write_hwaddr
is used.
