931e06de64 i.MX31/Gigabeat S: Actually enable DPTC which can set optimal voltage for 528MHz. Requires an SPI and PMIC interface rework because of the low-latency needs for the DPTC to work best with minimal panicing. SPI can work with multitasking and asynchronously from interrupt handlers or normal code.

b3f1eb8bba Gigabeat S: Those odd calls to irq_handler can still happen rarely after executing WFI. With no explanation forthcoming after trying many things, hide head in sand and ignore them and the IRQ will get vectored to the correct handler anyway. Have vector tables execute an immediate return and remove irq_handler from compilation altogether.

5b4a84a4ce FS#11149: alternative fix for ipod startup/shutdown issue 
Instead of using the OF's low-battery handler to force a shutdown which appears to have numerous unwanted side effects, just clear the end of IRAM before shutting down which appears to solve the original "ipod sometimes needs hard reset to turn on" issue.

If you experience the "need hard reset" issue after this commit, please let us know. It has been tested on several models but we still don't know for sure what the original problem was. ;)

845af676f8 as3525(v2): Add a somewhat inaccurate udelay (-0.5/+1.0µs). It should work good for some huge delays. 
Use it in fuzev2 to improve some big delays (correct the biggest one to actually wait for the fifo to empty), and use it in the sd drivers.
