Paul Gortmaker [Mon, 28 Jan 2008 07:27:51 +0000 (02:27 -0500)]
[POWERPC] QE: Explicitly set address-cells and size cells for muram

Currently there are several dts that don't specify address or size
cells for the muram.  This causes dtc to use default values, one of
which is an address-cells of two, and this breaks the parsing of the
muram ranges, which is assuming an address-cells of one. For example:

Warning (reg_format): "reg" property in
/qe@e0100000/muram@10000/data-only@0 has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 1)

Explicitly setting the address and size cells gets it parsed properly
and gets rid of the four dtc warnings.

[POWERPC] Reduce code duplication in legacy_serial, add UART parent types

The legacy_serial was treating each UART parent in a separate code block.
Rather than continue this trend for the new parent IDs, this condenses
all (soc, tsi, opb, plus two more new types) into one of_device_id array.
The new types are wrs,epld-localbus for the Wind River sbc8560, and a
more generic "simple-bus" as requested by Scott Wood.

This reverts commit 5c3f5892a2db6757a72ce8b27cba90db06683e1d,
basically because it changes behaviour even when no fake NUMA
information is specified on the kernel command line.

Firstly, it changes the nid, thus destroying the real NUMA
information.  Secondly, it also changes behaviour in that if a node
ends up with no memory in it because of the memory limit, we used to
set it online and now we don't.

Also, in the non-NUMA case with no fake NUMA information, we do
node_set_online once for each LMB now, whereas previously we only did
it once.  I don't know if that is actually a problem, but it does seem

[POWERPC] Enable RTC for Ebony and Walnut (v2)

This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

[POWERPC] PS3: Use the HVs storage device notification mechanism properly

The PS3 hypervisor has a storage device notification mechanism to wait
until a storage device is ready.  Unfortunately the storage device
probing code used this mechanism in an incorrect way, needing a
polling loop and handling of devices that are not yet ready.

This change corrects this by:
  - First waiting for the reception of an asynchronous notification
    that a new storage device became ready,
  - Then looking up the storage device in the device repository.

On shutdown, the storage probe thread is stopped and the storage
notification device is closed using a reboot notifier.

[POWERPC] kdump shutdown hook support

This adds hooks into the default_machine_crash_shutdown so drivers can
register a function to be run in the first kernel before we hand off
to the second kernel.  This should only be used in exceptional
circumstances, like where the device can't be reset in the second
kernel alone (as is the case with eHEA).  To emphasize this, the
number of handles allowed to be registered is currently #def to 1.

This uses the setjmp/longjmp code around the call out to the
registered hooks, so any bogus exceptions we encounter will hopefully
be recoverable.

Tested with bogus data and instruction exceptions.

14 years ago[POWERPC] Make smp_send_stop() handle panic and xmon reboot

[POWERPC] Make smp_send_stop() handle panic and xmon reboot

smp_send_stop() will send an IPI to all other cpus to shut them down.
However, for the case of xmon-based reboots (as well as potentially some
panics), the other cpus are (or might be) spinning with interrupts off,
and won't take the IPI.

Current code will drop us into the debugger when the IPI fails, which
means we're in an infinite loop that we can't get out of without an
external reset of some sort.

Instead, make the smp_send_stop() IPI call path just print the warning
about being unable to send IPIs, but make it return so the rest of the
shutdown sequence can continue. It's not perfect, but the lesser of
two evils.

Also move the call_lock handling outside of smp_call_function_map so we
can avoid deadlocks in smp_send_stop().
