In bcm5421_init(), we should call of_node_put() for the reference
returned by of_get_parent() which has increased the refcount.

powerpc's <asm/prom.h> includes some headers that it doesn't
need itself.
In order to clean powerpc's <asm/prom.h> up in a further step,
first clean all files that include <asm/prom.h>
sungem_phy.c doesn't use any object provided by <asm/prom.h>.
But removing inclusion of <asm/prom.h> leads to the following
errors:
CC drivers/net/sungem_phy.o

Remove <asm/prom.h> from included headers but add <linux/of.h> to
handle the above.

Add SPDX license identifiers to all files which:
- Have no license information of any form
- Have MODULE_LICENCE("GPL*") inside which was used in the initial
scan/conversion to ignore the file
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:
GPL-2.0-only

The object references of mii_phy_ops structures are only stored
in the ops field of a mii_phy_def structure. This ops field is of type
const. So, mii_phy_ops structures having similar properties can be
declared as const.

The sungem driver has "phy_read()" and "phy_write()" functions, which
we need to rename because the generic phy layer is about to export
generic interfaces with the same name.

Since sungem_phy is used by multiple, unrelated, drivers make it
build as a real module under drivers/net.
depmod will pick up the symbol dependency and make sure sungem_phy.ko
gets loaded any time sungem.ko or spider_net.ko is loaded.

Moves the Sun drivers into drivers/net/ethernet/sun/ and make
the necessary Kconfig and Makefile changes.
Oliver Hartkopp <socketcan@hartkopp.net> suggested removing the
sun* prefix on the driver names. This type of change I will
leave up to the driver maintainers.

while (limit--)
if (test())
break;
if (limit <= 0)
goto test_failed;
In the last iteration, limit is decremented after the test to 0.
If just thereafter test() succeeds and a break occurs, the goto
still occurs because limit is 0.

This version moves the medium variable to the card specific structure and
changes the GMII_* to BCM54XX_* #defines.
This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.
More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.
The patch moves the genmii_* functions around to avoid foreward declarations.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

This patch adds support for a few more PHYs used by Apple and fixes
advertising and detecting of Pause (we were missing setting the bit in
MII_ADVERTISE and weren't testing in LPA for all PHYs).
Note that I currently only advertise pause, not asymetric pause. I
don't know for sure the details there, I suppose I should read a bit
more 802.3 references, and I don't now what sungem is capable of, but
I noticed the PCS code (originated from you) does the same.

In a short discussion with Benjamin Herrenschmidt he mentioned
that Marvell PHYs are powered down the same way as the other
ones we currently handle. Thus actually do that, hopefully
saving some power during suspend.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
