We'd like to use cpuidle-arm.c for both arm and arm64 with psci as backend. For arm64, it works. But for arm, we miss cpuidle_ops, these patches try to address this issue.
Has been tested on Marvell Berlin SoCs. These patches are rebased on the Mark Rutland's latest psci unification work. [PATCH 1/3] renames psci_smp.c to psci.c to prepare for the next two changes. [PATCH 2/3] enables PSCI on UP systems so that some calls like cpu_suspend can be made functional on UP too [PATCH 3/3] add the cpuidle_ops for psci. Most code is stolen from arm64, which introduce duplicated psci code, that's why it's marked as "RFC", I dunno where to put cpu_psci_cpu_init_idle() related functions. Comments are welcome!
