9c52b24b00 patch #922836 by Jens: way faster disk writing, in assembler. The code is in, but yet disabled by #define PREFER_C_WRITING unless it's proven safe for all disks.

cb570b9263 Assembler optimized copy_read_sectors() gives another speedup of factor 1.4 for aligned and 1.2 for misaligned. Including my previous change the file reading is now nearly twice as fast compared to when I started this. -> Less disk uptime, longer battery life.

c546b70e18 Really squeezed lcd_write_data() with tricky assembler optimization. Now it does 114 fps when playing video from memory (way more than the ~75 fps needed, I need to slow down the video player), leaving headroom for audio.

26f42605c2 Reverted to the old ADC driver, since it appeared to cause fake OFF keypresses (weird indeed, since the OFF key doesn't use the ADC on the plain Recorder). However, I did fix the batch convert, since it caused fake keypresses at boot time.

88faf38ef7 Optimized the sector read loop as much as C allows. I measured an overall speed improvement for file reading of 12.5% for 16-bit aligned and 35% for misaligned. I took the rest of ata_read_sectors() out of IRAM, it's sufficient if only the copy loop stays there.

50b6358272 Craig Sather's patch #849405: 
This patch fixes two bugs associated with lcd_puts and scrolling on the
recorder.

1 - Unlike the implementation in the player code, on the recorder a call to
lcd_puts does not stop the scrolling text from a previous lcd_puts_scroll
call, so the new line gets overwritten by the old scrolling text. More
discussion and details can be found at:
http://rockbox.haxx.se/mail/archive/rockbox-archive-2003-11/0531.shtml

2 - When the function lcd_puts_scroll_style is called with an x offset greater
than 0, the scrolling text is placed at an offset of 2x instead of x.

5bd3297fd4 Faster, simplified A/D driver. The previous batch convert in init_adc() produced garbage because of the fast conversion time, causing fake keypresses that made ask_resume() return prematurely. This should fix the intermittent resume problem reported by many users.
