MIPS: fix memset()

2018-09-07T07:43:05+00:00

swr/swl instructions used for word aligning were wrong. This
made memset() terribly broken. I can't imagine how it went
uncaught for soooo long. Spotted by Solomon Peachy.

I run unit tests for alignments 0,1,2,3
size 1, 2, 3, 4, 5, 63, 64, 65, 127, 128, 129;
and fill pattern 0x00 and other (since 0 is special case in this
implementation).

Fix MIPS threading code to compile with older compiler

2018-06-12T10:41:03+00:00

Official rockbox mips gcc is old and doesn't support
symbolic register names in inline assembly

fix warning in lcd-as-memframe.c

2017-09-17T13:13:52+00:00

The fix is to actually remove unused variables. Those were unused from day 1,
which I find slightly suspicious so either there is some problem or the code was
copy-pasted and modified, making some variables useless.

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

This fixes the sgt-mines plugin. Same issue was present in an old
glibc as well:

Fix dangerous casts

2017-02-04T16:24:47+00:00

On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h

Renamed defines UNALIGNED to ROCKBOX_UNALIGNED - UNALIGNED is already

2017-01-15T20:32:49+00:00

defined in mingw environments.

Renamed defines of UNALIGNED to ROCKBOX_UNALIGNED so that they don't
conflict with definitions in mingw32 cross-compiling environments
(defined in _mingw.h).
