940e8990b5 PP502x: Make RAM physical addresses uncached. Cache the flash ROM on targets with one. Kill all the now unneeded cache flushing and i2s tweaking on e200 so clicking is no worry. Write the driver framebuffer at uncached addresses. Recording monitoring may be a little noisy in the left channel for the moment when not boosted and will be addressed. All seems to work as advertised including flash ROM dump.

e760ba5a04 Add some defines for pp502x. No guarantee as to full accuracy yet but that's not really too important. Use them in the code.

7914e90738 Commit a subset of the dual core changes that have to do with cache handling, stacks, firmware startup and thread startup. Tested on e200, H10-20GB, iPod Color and 5.5G. Thread function return implemented for all targets. Some changes to plugins to follow shortly.

174c7abdff Add some new findings to the PP header files. * Clean up ata-target.h for PP. * check_registers() seems to work fine on PP5002.

7b861eca95 More PP502x clock setup rework. This should fix the freezes on PP5020 once and for all. Enabled clock scaling for H10. * CPUFREQ_MAX changed to 78MHz * To be cleaned up soon.

7027c6a0f8 FS#7036: Power saving improvements for Sansa. Shutdown LCD controller when backlight is off and shutdown ATA controller when the disk isn't being accessed. Frequency scaling is not enabled yet as it was apparently causing some problems.

0a643b8d90 Fix some very probable typo's. 
CPU_INT_STAT is at 0x60004000, not 0x64004000.
CPU_HI_INT_STAT is at 0x60004100, not 0x64004100.
Fix wrong IRQ CLR addresses being used by system_init().

82f9056988 Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly.

169ebdbda7 Some more replacing of inl/outl with register #define's (doesn't change end-result binary). Add lots more #define's based on the ipodlinux wiki and some extrapolation. 
Also add PortalPlayer SoC version to the HW info debug screen.

3a6d4791d7 No functional changes, just reorganising code: 
1) Move ARC OTG USB (used in PP502x) driver code into it's own file, drivers/arcotg_udc.c. Hopefully in  the future we will be able to adapt more of the Linux driver and add it to this file.
2) Rename mx31.h to arcotg_udc.h to reflect the file the code came from. It's also a more accurate name for the USB controller.
3) Get rid of one more inl()/outl() in usb-pp.c and use the relevant #define instead.
4) Add dr_controller_stop(). Not used yet.

84b509dc43 FS#6554. Move bootloader code into a common file. Only PortalPlayer devices (iPods, H10, Sansa) are affected for the moment. Someone with access to (and no fear of bricking) an X5, H100, H300 and Gigabeat should try to adapt those bootloaders to also use the code in common.c. The (non-working) patch in the tracker would be a good place to start with this.

4b54302b07 Combine USB code for all PortalPlayer targets since they most likely all use the same USB hardware. Add register defines for the USB hardware addresses, based off the Freescale i.MX31 datasheet. Use usb_init() from the iPod code, but modified to use the new register defines rather than oul/inl on the hardware addresses.

e63e62b2a1 Detect charger connected on H10. No need to sleep(HZ) when powering off. 
More sensible USB support for H10: plugging in puts it into USB charging mode and leaves Rockbox usable, holding 'O' while pluggin in the USB cable will reboot the H10 (continuing to hold 'O' starts it up in UMS mode), holding any other button brings up the USB screen as previously.
Implement system_reboot() for all PP5020 devices.
