See arch/arm/include/asm/io.h for the respective I/O accessors.
As I have no idea which registers might be hidden by these magig
numbers 0xA0412900 or 0xA0412904 it's hard for me to find any good
example. See for example accesses like the
writel(val, &ccm->cgr0);
in arch/arm/cpu/arm926ejs/mx25/generic.c, etc. etc.
Best regards,
