Add jz4760 tool

2015-03-29T12:08:28+00:00

This tool can pack/unpack a jz4760 archive (like the one used for the fiio
x1/x3/x5), and can descramble/scramble (it's the same operation) a firmware
file (the sys.bin file in the archive). I did my best to keep the compatibility
with the leaked Fiio/Ingenic tool which has the same name.

I wrote the tools from scratch, but here are some remarks:
- the format used is a slightly modified IHFS used in the older JZ4640 series,
  I used the information on the wiki about the IHFS format
- the CRC computation done was already reversed engineered by someone on the
  forums but I realised this later
- There are a few unknown fields in the headers, see comments in the source code
- The firmware scrambling was discovered by pure guess, I realised there were
  some repetitve sequences, some I guessed it was a rotative XOR and ran some
  analysis to find the most probable sequence

qeditor: Add external static libraries to build dependecies

2015-03-04T21:46:03+00:00

The solution is a bit hacky as it simply call make in libs
directory as pre-dependency. Clean doesn't touch libs.

Introduce a new analysis tool to detect which macros are defined in each build.

See the usage() for more information.

atj213x: fix desc file errors

2015-01-22T12:38:13+00:00

Catched by swiss_knife check there are some overlaping fields
and invalid characters in some names.

Fix crash on uninitialized variable

2015-01-13T20:57:24+00:00

The WRITE() macro checks if the "fw" pointer
is open upon fwrite() error. Since fw was
not initialized before use, it might crash for non-zero fw.

cppcheck reported.
[utils/jz4740_tools/HXFreplace.c:187]: (error) Uninitialized variable: fw

Less code makes the compiler even happier.

jz4740 usbtool: Fix undefined behavior in set_reg()

2015-01-04T17:16:44+00:00

The variable 'i' should actually be 'size'.
See the read_reg() function above it.

Confirmed via private email from Maurus Cuelenaere. Thanks!
(who also remembered having trouble reading/setting
 registers over USB back then ;))
