* sparc32, leon: Enable interrupts before going idle to avoid getting stuckAndreas Larsson2013-06-191-0/+7
| | | | | | | | | | | | This enables interrupts for Leon before having the CPU enter power-down mode. Commit 87fa05aeb3a5e8e21b1a5510eef6983650eff092, "sparc: Use generic idle loop", gets the CPU stuck on idle for Leon systems. On Leon, disabling interrupts and powering down the processor will get the processor stuck waiting for an interrupt that will never be reacted to.

* sparc idle: rename pm_idle to sparc_idleLen Brown2013-02-171-2/+3
| | | | | | | | | | | | (pm_idle)() is being removed from linux/pm.h because Linux does not have such a cross-architecture concept. sparc uses an idle function pointer in its architecture specific code. So we re-name sparc use of pm_idle to sparc_idle. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: David S. Miller <davem@davemloft.net> Acked-by: Sam Ravnborg <sam@ravnborg.org>

* SPARC/LEON: power down instruction different of different LEONsDaniel Hellstrom2011-03-161-0/+82
The way a LEON is powered down is implemented differently depending on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB and CHIP. This is for example needed by the GR-LEON4-ITX board and the UT699. Previously the power down support for LEON was limited to SMP, now both SMP and UP systems use the instruction.
