Will fix RPI-B kernel build failure since it adds missing
armv6_idcache_wbinv_all which was previously taken from cpufunc_asm_pj4b.S.

r235816 triggered kernel panic or hang after warm boot.
Don't blindly restore BCE_EMAC_MODE media configuration in
bce_reset(). If driver is about to shutdown it will invoke
bce_reset() which in turn results in restoring BCE_EMAC_MODE
media configuration. This operation seems to confuse controller
firmware.

RTL8168GU has two variants(GMII and MII) but it uses the same chip
revision id. Driver checks PCI device id of controller and
sets internal capability flag(i.e. jumbo frame and link speed down
in WOL).

I don't have a copy of data sheet so I'm not sure exact PHY model
name. Vendor's web page indicates RTL8251 is latest PHY so I used
the name. This PHY is used with RTL8168G, RTL8168GU and RTL8411B.
the rate is 11n, rather than whether the channel is 11n.
This correctly allows the PLCP lookup code to return the legacy rates
even on an 11n channel.

to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual
machine was by presenting it as a PCI device that is mapped at the legacy
I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach:
- It did not work at all with UEFI because UEFI will reprogram the PCI device
BARs and remap the COM1/COM2 ports at non-legacy addresses.
- OpenBSD GENERIC kernel does not create a /dev/console because it expects
the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device.
- It was functional with a FreeBSD guest but caused the console to appear
on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it
is possible to have uart devices on the PCI bus in addition to the legacy
COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is
"-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is:
"-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is:
"-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.

Sheeva PJ4Bv6 - based chips were only prototypes for V7 class Armada
SoC family. Current in-tree support for PJ4Bv6 will not work and also
there should be no platforms in active use that would incorporate that
CPU revision.
Loading kernel to 0xf00000 has no practical reason.
Starting it from the u-boot's highest possible end address
(2MB counting from 0x0) makes more sense.

Depending on u-boot's flavor some boards have their SoC registers
base address configured to 0xD0000000 and other to 0xF1000000.
U-boot is passing currently set value via CP15 register.
In order to create proper mapping for SoC registers and allow further
successful initialization it is necessary to replace fdt_immr_pa with
the real value and eventually fix-up device tree blob.
Tested by: kevlo
Armada XP initialization flow requires SoC registers to be
mapped very early in order to configure Snoop Filter for SMP.
Additional mapping in locore.S is redundant as proper mapping is
made in pmap_devmap_bootstrap() prior to calling cpu_setup() which
configures the Snoop Filter.
For secondaru CPUs it is better to pass VA of the SoC
registers defined in MV_BASE and PA consistent with the value
in the Device Tree.
