MXC needs the same change as IOP. See [ARM] 4494/1
or commit 7dea1b2006
An undefined reference to elf_hwcap prevents linkage, due
to changes made by f884b1cf57
and d1cbbd6b41
Removing processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.

These patches add full SSP/MCU support for the HP Jornada 720
machine. Its needed to handle keyboard, touchscreen, battery
and backlight/lcd.
The main driver exports functions and the header file exports
the command values. When talking to the MCU the general procedure
is to start MCU, send command (using ssp_inout(command)), the
proper reply is always TXDUMMY. After receiving TXDUMMY you can
send the value you wish pushed (for example brightness level).
End with ssp_end() so the spinlock gets unlocked.
Drivers using this havent been implemented yet, but will shortly.

1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend
and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
the corresponding _suspend functions, thus remove all those ugly
#ifdef .. #endif out of sleep.S
2. move the declarations of those suspend functions to pm.h
note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is

1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific
operations as follows:
struct pxa_cpu_pm_fns {
int save_size;
void (*save)(unsigned long *);
void (*restore)(unsigned long *);
int (*valid)(suspend_state_t state);
void (*enter)(suspend_state_t state);
}
2. processor specific registers saving and restoring are performed
by calling the corresponding (*save) and (*restore)
3. pxa_cpu_pm_fns->save_size should be initialized to the required
size for processor specific registers saving, the allocated
memory address will be passed to (*save) and (*restore)
memory allocation happens early in pxa_pm_init(), and save_size
should be assigned prior to this (which is usually true, since
pxa_pm_init() happens in device_initcall()
4. there're some redundancies for those SLEEP_SAVE_XXX and related
macros, will be fixed later, one way possible is for the system
devices to handle the specific registers saving and restoring
