SUPPORTED SERIES:
- NWZ-E450
- NWZ-E460
- NWZ-E470
- NWZ-E580
- NWZ-A10

NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
  since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested

TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
  probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal

POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver

AMS: Return ascodec to interrupt-based I2C2 driver 2017-01-24T23:05:13+00:00 Michael Sevakis jethead71@rockbox.org 2017-01-21T13:04:43+00:00 783c77531c35e62dd754c510c4f2beefe6df4a9d 1. Slightly revised and regularized internal interface. Callback is used for read and write to provide completion signal instead of having two mechanisms. 2. Lower overhead for asynchronous or alterate completion callbacks. We now only init what is required by the transfer. A couple unneeded structure members were also nixed. 3. Fixes a bug that would neglect a semaphore wait if pumping the I2C interrupts in a loop when not in thread state or interrupts are masked. 4. Corrects broken initialization order by defining KDEV_INIT, which makes kernel_init() call kernel_device_init() to initialize additional devices _after_ the kernel, threading and synchronization objects are safe to use. 5. Locking set_cpu_frequency has to be done at the highest level in system.c to ensure the boost counter and the frequency are both set in agreement. Reconcile the locking inteface between PP and AMS (the only two currently using locking there) to keep it clean. Now works fine with voltages in GIT HEAD on my Fuze v2, type 0. Previously, everything crashed and died instantly. action.c calling set_cpu_frequency from a tick was part of it. The rest may have been related to 3. and 4. Honestly, I'm not certain! Testing by Mihail Zenkov indicates it solves our problems. This will get the developer builds running again after the kernel assert code push. Change-Id: Ie245994fb3e318dd5ef48e383ce61fdd977224d4

Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). 2010-06-21T16:53:00+00:00 Thomas Martitz kugel@rockbox.org 2010-06-21T16:53:00+00:00 35e8b1429a2cdcf6580f6d25890fed9865165d0b The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR). The new define is to (de-)select code to compile on hosted platforms generally. Should be no functional change to targets or the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27019 a1c6a512-1295-4272-9138-f99709370657
