The RVBAR_EL3 characteristics are:
If EL3 is the highest Exception level implemented, contains the IMPLEMENTATION DEFINED address that execution starts from after reset when executing in AArch64 state.
This register is present only when HaveEL(EL3). Otherwise, direct accesses to RVBAR_EL3 are UNDEFINED.
Only implemented if the highest Exception level implemented is EL3.
RVBAR_EL3 is a 64-bit register.
The RVBAR_EL3 bit assignments are:
63 | 62 | 61 | 60 | 59 | 58 | 57 | 56 | 55 | 54 | 53 | 52 | 51 | 50 | 49 | 48 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 | 39 | 38 | 37 | 36 | 35 | 34 | 33 | 32 |

Reset Address. The IMPLEMENTATION DEFINED address that execution starts from after reset when executing in 64-bit state. Bits[1:0] of this register are 00, as this address must be aligned, and the address must be within the physical address size supported by the PE.
Accesses to this register use the following encodings:
op0 | op1 | CRn | CRm | op2 |
---|---|---|---|---|
0b11 | 0b110 | 0b1100 | 0b0000 | 0b001 |
if PSTATE.EL == EL3 && IsHighestEL(EL3) then if IsFeatureImplemented("Morello") && !CapIsSystemAccessEnabled() && !Halted() then AArch64.SystemAccessTrap(EL3, 0x18); else return RVBAR_EL3; else UNDEFINED;
