83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

1fd92db83d net: cosmetic: Fix var naming net <-> eth drivers
Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.

This cleans up the temporary hacks that were added to this interface
along with the DM support.

This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).

da384a9d76 net: rename and refactor eth_rand_ethaddr() function
Some functions in include/net.h are ported from
include/linux/etherdevice.h of Linux Kernel.

For ex.
  is_zero_ether_addr()
  is_multicast_ether_addr()
  is_broadcast_ether_addr()
  is_valid_ether_addr();

So, we should use the same function name as that of Linux Kernel,
eth_rand_addr(), for consistency.

Besides, eth_rand_addr() has been implemented as an inline function.
So it should not be surrounded by #ifdef CONFIG_RANDOM_MACADDR.

5c1d082b14 DM9000:Add a byte swap macro for dm9000 io operation.
commit a45dde2293 changed the dm9000
direct register access to standard IO. This should work
on the ColdFire platform as there are corresponding macros for
the LE devices. But the hardware settings on some ColdFire boards had
swapped the byte order which make the original macros such as out_le16
cannot work. To avoid changing the common io access code on ColdFire
platform, the DM9000_BYTE_SWAPPED define was added to make the dm9000 use
__raw* IO access on some ColdFire boards.

09c04c2096 Remove instances of phy_read/write
There were a few files which were already using phy_read and phy_write
for their PHY function names.  It's only a few places, and the name
seems most appropriate for the high-level abstraction, so let's
rename the other versions to something more specific.

Also, uec_phy.c had a marvell_init function which I renamed to not
conflict with the one in marvell.c

Lastly, uec_phy.c was putting a space between the phy writing
function names, and the open paren, so I fixed that

67bee2fb64 net: dm9000x: re-add casts to I/O pointers to fix gcc warnings
The DM9000 in/out helper functions were casting the register address when
it was accessing things directly (pre commit a45dde2293).  But
when it was changed to using the in/out helpers, those casts were dropped
because those functions don't take pointers.  Even more recently, those
functions were then changed to use the read/write helpers, but the casts
were not re-added.  This is necessary because the read/write helpers do
take pointers.  Otherwise we get a lot of warnings like:
dm9000x.c: In function 'dm9000_inblk_8bit':
dm9000x.c:172: warning: passing argument 1 of 'readb'
	makes pointer from integer without a cast

0e38c938ed DM9000 fix status check fail 0x6d error for trizeps board
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.

850ba7555d DM9000: Make driver work properly for DM9000A
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.

a101361bfe DM9000: Add data bus-width auto detection.
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.
