The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.

dm9000 has code to detect and initialize external phy parts, but later
on in the code the part is forced to use the internal phy
unconditionally. Remove the unused/untested code.
change the GPIO initialization so that only the GPIO used as an
internal phy reset (hardwired in the chip) is set as an output. The
remaining GPIO need to be handled by board specific code to prevent
possible drive conflicts. Set as inputs for safety.
replace a few magic numbers with defines

The received status and len was in little endian
format and caused the ethernet unable to proceed
further. Add __le16_to_cpu() in dm9000_rx_status_8/16/32bit().

According to the Application Notes of the DM9000, only the 2 bits 0:1 of
the status byte need to be checked to identify a valid packet in the fifo
But, The several different Application Notes do not all speak the same
language on these bits. They do not disagree, but only 1 Application Note
noted explicitly that only these 2 bits need to be checked.
Even the datasheets do not mention anything about these 2 bits.
Because the old code, and the kernel check the whole byte, I left this piece
untouched.
However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so
it should work.
Notice, that the 2nd iteration through this receive loop (when a 2nd packet is
in the fifo) is much shorter now, compared to the older U-boot driver code,
so that we can maybe run into a hardware condition now that was never seen
before, or maybe was seen very unfrequently.
Additionaly added a cleanup of a stack variable.

A last minute cleanup before submitting the DM9000A patch series yesterday introduced
a bug in reading the rx-status registers in 32bit mode only.
This patch repairs this.

Some lines of the U-boot DM9000x driver are longer than 80 characters, or
need some other minor cleanup.

The DM9000A network controller does not work with the U-boot DM9000x driver.
Analysis showed that many incoming packets are lost.
The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to
check for a valid rx packet be done on the interrupt status register, not
directly by performing the dummy read and the rx status check as is currently
the case in the u-boot driver.
When the recommended poll is done as suggested the driver starts working
correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there
can be more than 1 package in the fifo at the same time.
The driver must perform the rx-status check in a loop and read and handle all
packages until there is no more left _after_ the interrupt RX flag is set.
This change has been tested with DM9000A, DM9000E, DM9000EP.

According to the application notes of the DM9000 v1.22 chapter 5.2 bullet 2, the
reset procedure must be done twice to properly reset the DM9000 by means of software.
This errata is not needed anymore for the DM9000A, but it does not bother it.
This change has been tested with DM9000A, DM9000E, DM9000EP.

The eth_send routine of the U-boot DM9000x driver does not match the
DM9000 or DM9000A application notes/programming guides.
This change improves the stability of the DM9000A network controller.

It seems that the debugging code of the DM9000x driver in U-boot has not been
compiled for a long time, because it cannot compile...
Also rearranged some loglines to get more useful info while debugging.

The U-boot DM9000x driver contains a compile time bus-width definition for
the databus connected to the network controller.
This compile check makes the code unclear, inflexible and is unneccessary.
It can be asked to the network controller what its bus-width is by reading bits
6 and 7 of the interrupt status register.
The linux kernel already uses a runtime mechanism to determine this bus-width,
so the implementation below looks somewhat like that implementation.
This change has been tested with DM9000A, DM9000E, DM9000EP.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
