What is attribute `init` and `uninit` used in element device/board memory #322

What is attribute init and uninit used in element device/board memory: https://open-cmsis-pack.github.io/Open-CMSIS-Pack-Spec/main/html/pdsc_family_pg.html#element_memory

Today's link scripts handle init/uninit independent from this attribute. It appears that the usage is historic and no longer relevant. See https://github.com/Open-CMSIS-Pack/devtools/issues/1718

In uVision' Options for target dialog the target tab's memory is populated by the memory elements from the device. RW Memories have a check-box "NoInit". If a linker script is automatically generated from this data the "NoInit" results in the use of UNINIT for this memory region.
