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 ?

If an processor supports both execution states (ie AArch32 and AArch64) then the register is mandatory.
It is used to request a soft reset specifying whether to reset into AArch32 or AArch64. This is the only way to swap EL3 between AArch32/AArch64.
