05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

8399749412 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.

6a8379674c Finally, out goes struct spinlock for anything but mutiprocessor targets where it becomes a reenterable corelock.

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.

a9b2fb5ee3 Finally full multicore support for PortalPlayer 502x targets with an eye towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties.

f265ee9cd5 * Don't touch the backlight(s) (and buttonlight) at backlight init in order to avoid a short flash when the lights are both disabled in the bootloader and in rockbox settings. * Properly reflect the backlight state set by the 1st/2nd gen bootloader.

0fac492c3d First step of powermanagement rework: * Move target specific stuff into target tree, starting with battery voltage tables and voltage reading. (This revealed some incorrect percent_to_voltage_charging mappings). * Voltage reading on 1st gen ipods is now correct. * Clean up obsolete config #defines.

021c0868dd iPod 2nd gen: * Fake battery voltage of 4.00V so rockbox doesn't shutdown (ADC is not yet implemented). * Fix button hold polarity for main rockbox. * Implement backlight inversion (the 1st/2nd gen backlight works in a way that makes the LCD look inverted when active). * Fix default contrast and clean up target tree.
