Initial commit for the Sony NWZ linux port

2017-09-05T19:42:12+00:00

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

ARM unwinder for thumb: Fix broken MOV opcode

2015-01-12T18:36:58+00:00

The origin of the register value was never
moved in the desired register state due to a typo ('rhs' vs. 'rhd').

While looking at the code, I noticed the action taken
for the register value is another copy'n'paste error
from the ADD opcode above -> it added to the register value
instead of MOVing the current value.

Patch submitted upstream.

cppcheck reported:
[lib/unwarminder/unwarm_thumb.c:473]: (warning) Redundant assignment of 'state.regData[rhd].o' to itself.

Fix return address when data_abort_handler skips faulting instruction.

2013-05-23T23:51:19+00:00

When writing a value to PC, execution continues at that location,
so subtracting 4 returns to the next instruction. Previously, two
instructions after the faulting instruction were being skipped, causing
safe_read functions to return true even if a data abort happened.
