Andreas Ferber 847253b948 MIPS: Fix SSB PCIcore IO resource management
The SSB PCIcore code reused the IO resource fixup code from the original
2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack
for doing PCI IO resource configuration back then (the boot loader
doesn't configure PCI devices on this platform).

However, this code is no longer necessary since the kernel now can do
PCI resource management fine all by itself, so remove the old code.

When removing the code, it becomes obvious that the mem_offset setting
in the PCIcore driver was wrong, however this was masked by the fixup
code before, except in a few cases involving yenta_socket. For BCM47xx,
the correct offset is 0, and since this is the only device using PCIcore
in host mode, the offset can simply be removed unconditionally.

Michael Buesch 9e095a687b ssb-pcicore: Fix IRQ-vector init on embedded devices
On embedded devices we must not route the interrupts through
the PCI core, if our host-bus is not PCI.

Michael Buesch 51e8b88590 ssb-pcicore: Remove b44 TPS flag workaround
Now that we fixed the TPS flag assignment in commit
b63009b456
we don't need the workaround for the bcm44xx chip anymore.

Michael Buesch aab547ce0d ssb: Add Gigabit Ethernet driver
This adds the Gigabit Ethernet driver for the SSB
Gigabit Ethernet core. This driver actually is a frontend to
the Tigon3 driver. So the real work is done by tg3.

Michael Buesch 61e115a56d [SSB]: add Sonics Silicon Backplane bus support
SSB is an SoC bus used in a number of embedded devices.  The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well.  The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.

This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.
