bnx: Add support for BCM5762 chips

Taken-from: tg3

kernel: Use DEVMETHOD_END in the drivers.

brgphy: Add BCM5718C, BCM54680, BCM54880, BCM54640, BCM54685 and BCM54881

brgphy: Remove debug prints

bge/bce: Use mii private data to pass various flags to brgphy

This unbreaks if_name support on bce(4) and bge(4). And this mechanism
is cleaner and easier to extend than checking if_name and access

This unbreaks if_name support on bce(4) and bge(4). And this mechanism
is cleaner and easier to extend than checking if_name and accessing
NIC drivers' softc.

bge/brgphy: Split PHY flags out of main flags

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

For a running bge(4), setting these sysctl variables will not take
effect immediately; they are committed to device in the upcoming
interrupt handler.

Add support for Broadcom NetXtreme II GigE. Jumbo buffer support

Thank David Christensen <davidch@broadcom.com> for sending us two

Thank dillon@ for providing a blazing fast machine and environment
to test the driver.
Also thank Walter <wa1ter@myrealbox.com> very much, who contacted
Broadcom for me :)

Add new devices support for bge(4)
- Recognize more devices, including PCI ids, chip ids and asic ids.
- Use meaningful macros to distinguish chip family and capability, instead of
test against chip id or asic id directly.
- Pack bool fields of bge_softc into bge_softc.bge_flags,
o bge_softc.bge_extram is gone, which was never adopted.
o Add flags for jumbo frame capability.
o Add flags for various chip families.
o Add flags for the bus types (PCI-e/PCI-X).
o Add flags for various PHY bugs, which will be used by brgphy.
- Fix the detection of the bus type (PCI-e/PCI-X). (*)
- Properly initialize PCI-X bge(4).
- Fix support for certain 575x/578x chips (*):
o Correct bge_{read,write}mem_ind() by clearing BGE_PCI_MEMWIN_BASEADDR
before returning.
o Use the appropriate register writing method when reseting the chip.
o Program the descriptor DMA engine correctly.
o Disable fastboot if the chips support it.
o Add some 'magical' magics on chip resetting path.

# (*) are done in if_bge.c rev 1.159 and 1.178 by scottl@freebsd.org and
# jkim@freebsd.org, based on code provided by David Christenson from Broadcom.


Adapt brgphy to work with the changes in bge(4)
- Recognize Broadcom 5755/5787 PHY.
- Add DSP code for various PHY bug workarounds.
- Detect PHY bugs based on the flags passed by bge(4) and load corresponding
workaround DSP code.
Obtained-from: OpenBSD

- Set PHY jumbo frame settings.

- Merge following link state detection fixes from FreeBSD:
if_bge.c rev 1.{102, 104, 113, 120, 124} (mainly oleg@freebsd.org)
Local modifications:
o Split bge_link_upd() into
bge_bcm5700_link_upd() -- for 5700 chips, except B2
bge_tbi_link_upd() -- for fiber interface
bge_copper_link_upd() -- for the rest for the bge(4) chips
Assign one of them to bge_softc.bge_link_upd based on chip type
in attach routine.
o Add bge_softc.bge_link_chg, which is setup based on chip type in
attach routine. It is used to check against MAC_STS to determine
whether link state is changed or not.
o We always trust that "link state changed" bit in MAC_STS is correct.
o Keep the PCS error checks for fiber interface during link state
changing detection.
- After above change, bge_tick() is used to drive mii_tick(), so cleanup
brgphy_mii_phy_auto().
- In brgphy_status(), use temporary variable to hold BRGPHY_MII_AUXSTS,
so it is not accessed twice.
- For fiber interface, correct media status reporting if link is down.
Obtained-from: OpenBSD (brad@openbsd.org)
- Correct chip id for 5700 B1 and 5700 B2.
- Minor style changes.

Do a major clean-up of the BUSDMA architecture. A large number of
essentially machine-independant drivers use the structures and definitions
in machine-dependant directories that are really machine-independant in
nature.

Split <machine/bus_dma.h> into machine-depdendant and machine-independant parts
and make the primary access run through <sys/bus_dma.h>.

Remove <machine/bus.h>, <machine/bus_memio.h> and <machine/bus_pio.h>. The
optimizations related to bus_memio.h and bus_pio.h made a huge mess,
introduced machine-specific knowledge into essentially machine-independant
drivers, and required specific #include file orderings to do their job.
They may be reintroduced in some other form later on.

Move <machine/resource.h> to <sys/bus_resource.h>. The contents of the file
is machine-independant or can be made a superset across many platforms.

Make <sys/bus.h> include <sys/bus_dma.h> and <sys/bus_resource.h> and
include <sys/bus.h> where necessary. Remove all #include's of
<machine/resource.h> and <machine/bus.h>. That is, make the BUSDMA
infrastructure integral to I/O-mapped and memory-mapped accesses to devices
and remove a large chunk of machine-specific dependancies from drivers.
bus_if.h and device_if.h are now required to be present when using <sys/bus.h>.

Sync MII support with NetBSD/OpenBSD:
- Standard conforming GMII support:
1) replace mii_media_add() with mii_phy_add_media().
2) ukphy has generic GMII support now, thus retire nvphy.
- Factor common code of PHY modules out into mii_physubr.c, noticably
mii_phy_{set_media, tick, update}().
In order to support this refactoring:
1) mii_softc.{mii_reset,mii_status} funtion pointers are added, which are
used to reset PHY modules and get PHY modules' status.
2) mii_softc.mii_anegticks is added, which is used by PHY modules to tell
mii_phy_tick(), how often auto-negociation should happen. Two commonly
used values are defined as MII_ANEGTICKS and MII_ANEGTICKS_GIGE.
mii_softc.mii_anegticks is set to MII_ANEGTICKS by default.
- Add mii_softc.mii_media_status and rename mii_softc.mii_active to
mii_softc.mii_media_active. Now changes in either one of them will cause
MIIBUS_STATCHG() being involked.
- For PHY modules that utilize mii_phy_add_media(), ifmedia_entry.ifm_data
no longer stores value of BMCR. It stores an index of mii_media_table[],
which stores BMCR, ANAR and GTCR.
- Replace slightly different PHY modules detach routines with ukphy_detach().
- Use OUI and MODEL id array + mii_phy_match() in PHY modules probe routines,
instead of original large `if, else if' or `switch' code segment.
- Support more OUIs and MODELs in individual PHY module.
- Make the usage of `mii' and `sc' stack variable more consistent. `mii'
refers to miibus softc, while `sc' refers to PHY module softc.
- Nuke no longer used functions' definition and declaration.
- Regen miidevs.h

Following PHY modules were tested:
acphy(dc), brgphy(bge), e1000phy(nv,sk), exphy(xl), inphy(fxp), rgephy(re),
rlphy(rl), ruephy(rue), ukphy(nv,vr,...)

MII generic code is mainly synced with NetBSD.
Individual PHY modules are mainly synced with OpenBSD.
