It was already defined in target-arm/helper.c file. Could you elaborate
which part is missing?
{ .name = "PMINTENCLR_EL1", .state = ARM_CP_STATE_AA64,
.opc0 = 3, .opc1 = 0, .crn = 9, .crm = 14, .opc2 = 2,
.access = PL1_RW, .accessfn = access_tpm, .type = ARM_CP_ALIAS,
.fieldoffset = offsetof(CPUARMState, cp15.c9_pminten),
.writefn = pmintenclr_write },
