printf ("attempting cpu_uid read\n");
u32 cpu_uid = *((u32 *) 0x48002318);
/* u32 cpu_uid = readl(&ctrl_base->randkey_0); */
printf ("cpu_uid read done\n");
This does hang after first printf, second printf is never printed.
Both, the direct register access and the readl style doesn't work.
Access to other system control module register in the same address
range works fine, though.
Any idea or hint?
