Uses GPIO.E2 (Request To Send) to detect the holdswitch status,
it is a temporal workaround that seems to work on all models.
Holdswitch status must be detected to drive low GPIO.E2 (RTS)
and GPIO.E4 (Data Out) when the holdswitch is locked, otherwise
battery life decreases about 25%.
Holdswitch unlock action is detected by reading the HELLO message
that the external wheel controller sends when it is powered on,
this allows to quickly capture clickwheel activity after unlock.
GPIO.E2 is also used in case the HELLO message is missed because
the holdswitch was unlocked before Rockbox/bootloader starts.
These 2 lines (RTS and DOUT) can not be used to transmit messages
to the external clickwheel controller, not a problem, actually no
messages are sent while normal operation, only at initialization
stage.

This restores functionality that was broken in g#194 and committed as
revision 7ec426e497.
Bidirectional communication is required to ask the clickwheel controller
for the initial button state during boot. Otherwise our driver would only
know about pressed buttons when the first change event is received,
which is too late for e.g. prevention of USB connection during boot.
This fix is also required to support the selection of OF, Rockbox,
Disk Mode, etc. in the iPod Classic Rockbox bootloader.

These nearly identical files are multiplying like rabbits as PP targets
are added and make SoC-related changes a PITA. Just include the master
.lds file from the target one as was done for bootloader USB.

polling the PMU via I2C, this fixes some random crashes

Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

* 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.

Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections,
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.

Since memory on 32mb ipod videos is mapped twice, a 64mb build still has codecs and plugins mapped in a usable area. This means that all that needs to be done to support 32mb and 64mb boards with the same build is to adjust audiobufend to avoid using more than the actually present RAM.
