* [POWERPC] Add definition of Cell bookmark SPRGeoff Levand2008-01-251-0/+1

* [POWERPC] kdump shutdown hook supportMichael Neuling2008-01-252-5/+99
| | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Make setjmp/longjmp code usable outside of xmonMichael Neuling2008-01-255-70/+86
| | | | | | | | | This makes the setjmp/longjmp code used by xmon, generically available to other code. It also removes the requirement for debugger hooks to be only called on 0x300 (data storage) exception.

* [POWERPC] Export copy_page() on 32bitJoseph Fannin2008-01-251-0/+1
| | | | | | | | | | Export copy_page() on 32-bit powerpc; unionfs needs it. Unionfs already builds as a module on 64bit powerpc, so the export is placed within an existing CONFIG_PPC32 #ifdef. Signed-off-by: Joseph Fannin <jfannin@gmail.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Make smp_send_stop() handle panic and xmon rebootOlof Johansson2008-01-251-8/+29
| | | | | | | | | | | | | | | | | | | | | | 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().

| * [POWERPC] 85xx: Respect KERNELBASE, PAGE_OFFSET, and PHYSICAL_START on e500Dale Farnsworth2008-01-232-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | The e500 MMU init code previously assumed KERNELBASE always equaled PAGE_OFFSET and PHYSICAL_START was 0. This is useful for kdump support as well as asymetric multicore. For the initial kdump support the secondary kernel will run at 32M but need access to all of memory so we bump the initial TLB up to 64M. This also matches with the forth coming ePAPR spec.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With that patch fixed.c now fully emulates MDIO bus, thus no need to duplicate PHY layer functionality. That, in turn, drastically simplifies the code, and drops down line count. As an additional bonus, now there is no need to register MDIO bus for each PHY, all emulated PHYs placed on the platform fixed MDIO bus. There is also no more need to pre-allocate PHYs via .config option, this is all now handled dynamically.
