lcd drivers: Convert lcd_[remote_]framebuffer to a pointer

2012-02-28T00:44:59+00:00

Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

Increaase default ipod 3g contrast, to a value between the last two.

It seems there is some significant variance between different greyscale ipods of the same model, so it's unlikely that *any* value will be great for everyone. I'm hoping that this is just high enough that the lightest screens aren't totally blank, but not dark enough that the darkest screens are entirely unreadably black ;)

This rather unsatisfactory compromise is to help us get a new bootloader release out (since bootloaders can't have their contrast adjusted) - a real fix would be to detect the LCD type, which the OF appears to be able to do (maybe).

Greyscale iPods: Fix the default contrast in the bootloader and the core before settings are loaded. Especially important on 1st..3rd Gen as we're setting up the LCD controller quite a bit different than the OF on those.

Greyscale ipods: Use a somewhat darker shade for lightgrey, improving appearance.

Greyscale library: Optionally put the greyscale ISR on COP on portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen.

1st/2nd Gen: Backlight inversion needs to be protected from interrupts, because it can happen any time, even while the greyscale lib or something else is writing to the LCD from an ISR. Also make backlight inversion only hit the LCD if necessary. * Use register definition in the 1st..3rd Gen backlight drivers.

LCD driver tweaks for greyscale iPods: * Use 1/7 bias, 5x step-up and the highest step-up frequency on all 1st..3rd gen iPods, simplifying the driver this way. The default contrast for those iPods has changed - reset settings in case the display becomes unreadable. * Set n-line inversion drive to 9 lines, improving image quality on 1st..3rd gen iPods somewhat.
