Hi Experts,
Does the Reset Management Register will be implemented mandatory or optional for the SoC based on ARMv8 and how it is practically used ?

In addition to what Pete said, keep in mind that setting the RMR_ELx.RR bit is only a request for a warm reset, it doesn't actually necessarily do anything by itself. For example, on ARM's Cortex-A57, setting this bit simply asserts the WARMRSTREQ signal. It's then up to the SoC to do something with this, so for example the signal being asserted could cause a power controller to warm reset the core.
