I found it in an old m68k diff:


#define APUS_PROGRESS(_a)                      \
       lis     r3,0xfff0;                      \
       ori     r3,r3,0xeff0;                   \
       lis     r4,0x1234;                      \
       ori     r4,r4,(_a);                     \
       stw     r4,0x0(r3);                     \
       dcbf    0,r3;                           \
       sync;                                   \
       isync


So it's 0xeff01234 .
