Sorry guys, this patch raises compiler errors.

machine_is_apx4devkit is undefiend.

Shawn: Should we temporary add following lines into headers? Any better suggestions?

#ifndef machine_is_apx4devkit
#define machine_is_apx4devkit() 0
#endif

#ifndef MACH_TYPE_APX4DEVKIT
#define MACH_TYPE_APX4DEVKIT 0
#endif

Why can't we simply use HW_DIGCTL_CHIPID? This register is at 0x8001c310 for both, MX23 and MX28.

This is a fairly good suggestion. I will try to sort it out tomorrow.
