ssb: fix NULL ptr deref when pcihost_wrapper is used

2010-05-28T17:57:01+00:00

Ethernet driver b44 does register ssb by it's pcihost_wrapper
and doesn't set ssb_chipcommon. A check on this value
introduced with commit d53cdbb94a52a920d5420ed64d986c3523a56743
and ea2db495f92ad2cf3301623e60cb95b4062bc484 triggers:

pcmcia: re-work pcmcia_request_irq()

2010-05-10T08:23:13+00:00

Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:

- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
  clean up automatically on calls to pcmcia_disable_device() or
  device ejection.

- drivers still not capable of IRQF_SHARED (or not telling us so) may
  use the deprecated pcmcia_request_exclusive_irq() for the time
  being; they might receive a shared IRQ nonetheless.

ssb: Make bus registration failure not be silent

2010-04-26T18:21:23+00:00

In kernel Bugzilla #15825, a case where routine ssb_bus_pcibus_register()
fails silently is reported. The cause for the failure is still being
investigated; however, the diagnosis would be easier if the failure
had been reported.

ssb: Look for SPROM at different offset on higher rev CC

2010-04-26T17:51:08+00:00

Our offset handling becomes even a little more hackish now. For some reason I
do not understand all offsets as inrelative. It assumes base offset is 0x1000
but it will work for now as we make offsets relative anyway by removing base
0x1000. Should be cleaner however.

ssb: do not read SPROM if it does not exist

2010-04-26T17:50:54+00:00

Attempting to read registers that don't exist on the SSB bus can cause
hangs on some boxes.  At least some b43 devices are 'in the wild' that
don't have SPROMs at all.  When the SSB bus support loads, it attempts
to read these (non-existant) SPROMs and causes hard hangs on the box --
no console output, etc.

This patch adds some intelligence to determine whether or not the SPROM
is present before attempting to read it.  This avoids those hard hangs
on those devices with no SPROM attached to their SSB bus.  The
SSB-attached devices (e.g. b43, et al.) won't work, but at least the box
will survive to test further patches. :-)

MIPS: Fix SSB PCIcore IO resource management

2010-04-12T16:26:14+00:00

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.
