Don't have tools to hand, but wouldn't these work?

unsigned int foo = 1234;

  LDR R0, =&foo

  LDR R0,[R0]

 MOV R4, param1

If not, try reading the docs.

unsigned int bar(unsigned int r0)

{  unsigned int r1;  unsigned int r4 = 1234;        __asm    {        mov r1, r0        add r1, r4    }      return(r1);}
