63404a7d5d Separate running an SDMA channel from resetting it. It should make usage more flexible since resets are needed only before restarting if aborting transfers (because the script is left awaiting requests, not the next start) which PCM does alot of but other things likely won't.

21f0c9a282 Make basic cache functions into calls, and get rid of CACHE_FUNCTION_WRAPPERS and CACHE_FUNCTIONS_AS_CALL macros. Rename flush/invalidate_icache to cpucache_flush/invalidate. They're inlined only if an implementation isn't provided by defining HAVE_CPUCACHE_FLUSH/INVALIDATE.

e2a169bce5 Gigabeat S: Get remote keymaps up to snuff and working. Do a couple tweaks on main unit ones. Cleanup keymap file a bit. Fix main button scanner to not clobber remote button. Fix a bug in actions.c where 'LAST_ITEM_IN_LIST' didn't really terminate scanning immediately. It would do an additional call into get_context_map and silently pick up ACTION_STD.

1a00056f1f i.MX31: Make SPI more tolerant by resetting and forcing a reconfigure of the interface if an error ever happens. Better handle PMIC GPIO interrupt; it definitely doesn't low-pulse PRIINT (remains high if sources become active again or stay active while acking) so needed rising edge may never happen in such a case-- use high-level detection rather than rising edge. Optimize the reg/clr/set/mod functions a bit since they get more regular use now.

bf1cddf3e8 Hopefully make some progress against FS#9831. iPod Video seems fine now under XP at least. Move false reset detection to the USB target code. Gigabeat S works using the OTG module upon bus reset. Portal Player targets verify that the USB pin detect is ok upon bus reset.

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.

Get rid of USB charging option on targets that don't support it or don't implement it yet. Menu string remains to avoid language incompatibility but should be removed on next cleanup for targets not using it (notice in english.lang). global_settings becomes incompatible for some builds and so plugin API version is incremented.
