Error generation on accessing Special purpose register.

nancy

I am trying to write on a register using the following command:

asm("ldr r0, =0x00");

asm("MSR ICC_SEIEN_EL1, r0") ;

and getting this error:

tmp/ccnn8Apc.s: Assembler messages:

/tmp/ccnn8Apc.s:93787: Error: selected processor does not support requested special purpose register -- `msr ICC_SEIEN_EL1,r0'

Can somebody help me in finding out the root cause of this issue.
