2022-07-18ARM: mach-qcom: Add support for MSM8909Stephan Gerhold1-0/+1
Add a Kconfig entry for MSM8909 and the "qcom,msm8909-smp" CPU enable-method. The ARM Cortex-A7 cores are booted just like on MSM8226.

2022-02-03firmware: qcom: scm: Drop cpumask parameter from set_boot_addr()Stephan Gerhold1-2/+1
qcom_scm_set_cold/warm_boot_addr() currently take a cpumask parameter, but it's not very useful because at the end we always set the same entry address for all CPUs. This also allows speeding up probe of cpuidle-qcom-spm a bit because only one SCM call needs to be made to the TrustZone firmware, instead of one per CPU. The main reason for this change is that it allows implementing the "multi-cluster" variant of the set_boot_addr() call more easily without having to rely on functions that break in certain build configurations or that are not exported to modules.

2021-10-23ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226Stephan Gerhold1-0/+1
Unfortunately, some MSM8916 devices have signed firmware without ARM64 and PSCI support and can therefore only boot ARM32 Linux. The ARM Cortex-A53 cores should be actually booted exactly like the Cortex-A7 cores on MSM8226, so just add an alias for the existing code.

2019-02-01ARM: qcom: remove unnecessary boot_lockRussell King1-26/+0
The boot_lock is something that was required for ARM development platforms to ensure that the delay calibration worked properly. This is not necessary for modern platforms that have better bus bandwidth and do not need to calibrate the delay loop for secondary cores. Remove the boot_lock entirely.

2015-10-22ARM: Remove __ref on hotplug cpu die pathStephen Boyd1-1/+1
Now that __cpuinit has been removed, the __ref markings on these functions are useless. Remove them. This also reduces the size of the multi_v7_defconfig image: $ size before after text data bss dec hex filename 12683578 1470996 348904 14503478 dd4e36 before 12683274 1470996 348904 14503174 dd4d06 after presumably because now we don't have to jump to code in the .ref.text section and/or the noinline marking is removed.

This makes it easy to add SMP support for new devices by keying on a device node for the release sequence. We add the enable-method property for the cpus property to specify that we want to use the gcc-msm8660 release sequence (which is going to look for the global clock controller device node to map some Scorpion specific power and control registers). We also remove the nr_cpus detection code as that is done generically in the DT CPU detection code.
