default PM_CPU_RETENTION_DYNAMIC
help
In light sleep mode, certain CPU states and data need to be preserved in memory while cpu domain
is powered down. This configuration determines how the required memory resources are allocated.
The PM_CPU_RETENTION_DYNAMIC option allows more flexible runtime memory management by
supporting access to larger memory. However, it carries the risk of insufficient memory
when the chip enters the light-sleep mode, even resulting in retention failure.
In contrast, the PM_CPU_RETENTION_STATIC option ensures reliable sleep CPU retention during the
system initialization, but reduces the memory available during runtime.
