This is code is intended to development into a library of code for the NWZ that will be useful to write the "bootloader" on those device. At the same time, it comes with test programs that are easy to run in firmware upgrade mode and also provide a great test bench for the library. At the moment, two test programs are available: - test_display: simply prints two messages using /usr/bin/lcdmsg - test_keys: displays input key event Change-Id: I9d214894ffc9127b528fcdd3eb5d6b61f4e657a7

/* The Sony icx_key driver reports keys via the /dev/input/event0 device and
|
|
* abuses the standard struct input_event. The input_event.code is split into
|
|
* two parts:
|
|
* - one part giving the code of the key just pressed/released
|
|
* - one part is a bitmap of various keys (such as HOLD)
|
|
* The status of the HOLD can be queried at any time by reading the state of

|
