After placing the firmware.mi4 file in the root dir of the player in UMS mode of
the OF, Sansa should do stupid blinking with the backlight and buttonlight
alternately. Recovering from this state is possible through the recovery mode
(see Wiki), by putting an original copy of the firmware.mi4.

On the ZEN, the LCD is fed continuously by the DMA and this refresh needs to
be stop when the bootloader gives control to the firmware, otherwise the DMA
will source data from invalid region and it might even lock-up if the new
code touches the memory setup. Work around this by properly stopping the LCD
driver: the bootloader assumes that if the target defines HAVE_LCD_ENABLE
in bootloader build (which is unusual) then it needs to stop the LCD. Since
stopping the LCD could produce funny screens, power down backlight
which is expected to power down the LCD too, giving a nice black screen
instead of some random pixels.

HiFi E.T. MA8 is almost the same as MA9 except
another DAC(pcm1792 in ma8, df1704 in ma9).
MA8 has ILI9342 lcd, MA8C has ILI9342C lcd.

The only difference between this target and HiFi E.T. MA9
is display driver (ILI9342 in MA9 and ILI9342c in MA9C)

The bootloader must call disk_init_subsystem() because it is multithread
(because of USB), otherwise strange things might happen. Calling disk_init()
is unnecessary since it is call when mounting partitions.

Many imx233 targets boot in a very low performance mode, typically cpu and
dram at 24MHz. This results in very slow boots and very unstable USB
bootloader mode. Since cpu frequency scaling is disabled in bootloader in
rockbox, always make the frequency scaling code available and boost at boot
time.

The idea is to share loading code between bootloaders and rolo().

What it does:
- removes unnecessary file operations for the OF (one lseek() and one read() per one key),
- simplifies the code and reduces the code size.
Speedup is not noticeable but theoretically some is.

We know about two different bootroms. First can be found in rk2706A,
the second in rk2706B and rk2705. This two versions are very
similar but memory addresses are different. It seems it is possible
to distinguish bootrom version by reading SCU_ID register.

This change replaces an odd way to increment tea key in a function responsible
for finding the proper key (it doesn't have to be done in a for loop, it's just
adding a 32bit number to a 128bit number). It reduces the time needed to find
the key practically to zero and it gives in the best case 2 seconds of overall
speedup in loading the OF.

need to be dealt with, so do it the proper way.

* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application)
to break powermgmt.c's assumption about the ability to read battery voltage.
There's now additionally percentage (android) and remaining time measure
(maemo). No measure at all also works (sdl app). If voltage can't be measured,
then battery_level() is king and it'll be used for power_history and runtime
estimation.
* Implement target's API in the simulator, i.e. _battery_voltage(), so it
doesn't need to implement it's own powermgmt.c and other stubs. Now
the sim behaves much more like a native target, although it still
changes the simulated battery voltage quickly,
* Other changes include include renaming battery_adc_voltage() to
_battery_voltage(), for consistency with the new target functions and
making some of the apps code aware that voltage and runtime estimation
is not always available.

Synchronous cable read is still required because the timing of the receipt of
the cable event cannot be known for sure-- basically it introduced a thread
race between main and pmic. If a keypress is desired instead to enter BL USB
mode a la AS3525, then it's possible to remove that.
