837012be86 Fix graphical glitches occuring in the greyscale library on H1x0 and M5 at 124MHz. The main loop within lcd_grey_data() needed instruction reordering (interspersing lcd writes with memory accesses) to meed the LCD controller timing. Slight slowdown because of the extra register needed.

6a56c14e17 Greyscale library: Changed the internal data format once more (separated pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing.

feb5b15e9b All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.

ef12b3b5c6 Hardware controlled backlight brightness for iPod Video and Nano, retaining the software PWM fade in/ fade out. * Backlight handling cleanup, getting rid of one layer of 'lowlevelness'. * Use atomic GPIO bit manipulation for PP502x backlight handling.

b85b6be3aa Coldfire targets: enable buffered writes by default. Speeds up all sorts of I/O that writes to ports: LCD update (except the functions using DMA on H300), ATA writes, .... Some timings had to be adjusted for the new configuration.

f28da1a35a Enable a lot more features for simulators and add stubs where necessary, simulators should now work with identical lng and voice files as the respective target

2d48d0ffa6 Straighten out some audio path APIs and misc. audio stuff. Having recording is not a prerequisite to having input/output source selection which is probably most useful when adding a audio input features like FM to a new port without forcing recording to be implemented first.

47bf6c5a5a Moved archos backlight code to target tree. Changed old mutlivalue CONFIG_BACKLIGHT to a simple HAVE_BACKLIGHT.

633f388002 Coldfire targets: Shuffle IRQ levels around to have all interaction between low level audio function calls and DMA be atomic. Make recording and playback independently startable and stoppable so one can be running and not interfere with the other. All tests I can do at the moment check out ok (play, record, play+record, FM radio on iRivers, S/PDIF on H120 (w/running optical on/off), and on-the-fly samplerate changes). Recording tested for well over an hour run and no problems.

611737bde8 Add extra filtering to the X5 and M5 button drivers to prevent erratic button events (ported from H300).

8867d00141 More catching up on old work. Refine audio interface setup on Coldfire. Stop the funky glitching on the iAudio stuff when starting recording esp. at 88.2kHz. (probably due to the bidi interface). iRivers don't seem to care what you do. TLV320 still seems to have a little trouble selecting it's filters correctly for 88.2kHz or it could be some odd phasing effect. Get rid of the horrible reset parameter in pcm_apply_settings as it can decide for itself.

8876018d25 Bring up the M5 port to a working stage: Extended numerous explicit checks for IAUDIO_X5 to also check for IAUDIO_M5, moved code around the target tree, added preliminary background for the sim.
