* Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz2010-05-06
| | | | | | | | directory, also standard'ify some parts of the code base (almost entirely #include fixes). This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657

* Commit part of FS#9873 - Utilise buttons for playlistingThomas Martitz2009-07-22
| | | | | | | It adds a shortcut (combo or button) to directly go from the wps to the playlist viewer. The combos could possibly be improved on some targets, but I tried to keep a tad bit of consistency (was hardly possible). I also added a corresponding touchscreen region and adapted cabbiev2. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22003 a1c6a512-1295-4272-9138-f99709370657

* Core JPEG decoder improvements:Andrew Mahone2009-06-19
| | | | | | | | | For >8-point vertical IDCT, transpose the coefficients while decoding them, so that the vertical IDCT can read in rows rather than columns. This improves speed a bit for this size even using the C IDCT. Remove inline ARM asm, replacing it with an external file containing pure asm IDCT functions. Add jpeg_ prefix to JPEG IDCT functions since some of them will now be visible globally. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21345 a1c6a512-1295-4272-9138-f99709370657

Most notable speedups: 1 bit lcd driver: drawpixel +20%, drawline + 27%, hline +5%; jpeg viewer: +8% for 1/8 scaling.
