ffefe0c08b Put TIMER_FREQ definition in CPU-specific config, and remove timer-target.h 
Note : SH has TIMER_FREQ defined to CPU_FREQ, so any code wanting it must include #config.h before #cpu.h

b1dccc47fd PP502x: Improve accuracy of header file. It looks as though DMA channels share the same interrupt enable (tested that 0 and 2 do at least).

6c399b8254 Use DMA for audio playback on PP502x (FS#9910 + some further mods). I can't say at this point about any change in battery life but it frees up a percent or two of CPU cycles as measured in the buffering screen. No change in recording transfers yet. Testing seemed to check out so put it out for general use and see what happens.

da76a34694 Use bus reset detection for all ARC OTG devices. Remove conflict from LV24020LP driver with some GPIO-by-number macros for PP502x. Start monitoring for USB stack once all core threads and queues are created otherwise queues will likely be registered after USB acks. Putting PP502x system_reboot in IRAM (unmapped, uncached) memory seems to help it work more consistently. Hopefully I got all the PP USB connect handlers in the right spot in irq_handler. If device seems unresponsive to cable, check there first.

616c98b38f USB detection changes. c200/e200: Consider USB to be powered when charger is plugged but detect USB connection by bus reset. When received, disconnect and restart the driver fully enabled. imx31: Fix hack used to make initial connect succeeded-- set PHY type before initial reset. General: Move some target code out of usb-drv-arc.c and implement it in respective usb sources and CPU headers so things stay clean.

191320cd0f Rename CPU/COP_INT_CLR to CPU/COP_INT_DIS since it's really a 'write one to disable' register and hasn't anything to do with acknowledging interrupts-- that's handled at the module level.

054447f9e6 Commit FS#8379 by Andree Buschmann. Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices. For now, leave base CPU clock at 30MHz, although further savings is possible with some codecs if clock is reduced. Additionally, fix battery capacity on c200 and use my measurements to improve runtime estimation for Sandisk targets.

6fb4c53fb9 The GPIO interrupts are split into several port groups on all PP502x versions, so move those definitions into pp5020.h, and add the missing group. Make microSD hotswap detection work on Sansa c200. Note that microSD access itself does not work yet.

1d1a17c0db Improved H10 ADC driver. We now do things exactly as the OF does. This includes shifting the readings by 0x14 when PLL is enabled. Battery voltages and remote/scrollpad values adjusted accordingly. We also now wait for the ADC to indicate the conversion is complete before reading the data, so hopefully we will get more reliably steady readings.

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.

8aeed2d32e PP LCD drivers: * Optimised and cleaned up PP colour LCD drivers. Immeasurable speedup on iPod Color, huge speedup on small H10 (a factor of 3). Should be a bit faster on big H10 too. * Big H10 changed bitmap format, so needs reconfiguring + full rebuild. * Better register naming for the mono LCD bridge. Register names for the colour LCD bridge.

All seems to work as advertised including flash ROM dump.

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.

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.
