a36a498c57 i.MX31/Gigabeat S: This should fix stability problems. One problem was to start using the DVFS controller properly so that interrupts will be masked at the lowest and highest frequency indexes. Millions of useless interrupts were occurring at 132MHz because its index was 2, not 3, which masks it automatically when it can't go slower. Stopping the flood was enough to actually see the difference in general. IRQ must be disabled when fiddling with the CCM registers and only enabled when waiting for voltage ramp as having them enables also causes spurious DVFS ints. Implement interruptible ISR pro/epilogue more safely (always using IRQ stack even in SVC mode handling). Fix an improper inequality in DVFS code (which set regs for down when going up and v.v.). Misc. support changes. Have internal tables take less RAM.

8fd3ec9727 sd-as3525v2.c: Set MCI interrupt mask immediately prior to enabling DMA for the transfer. 
These INT's shouldn't be unmasked until the transfer is just about to happen.

630b4fc555 i.MX31/Gigabeat S: The nested IRQ code was just totally wrong and not actually working anyway (which is why it wasn't crashing). AVIC doesn't seem truthful about priority of current ISR either :\. Sometimes there were channel swaps during really active DVFS due to FIFO underflow from a needed long delay in the ISR (100us, and IIS TX only has 45us reserve) and DMARQ *must* be serviced low-latency. Get it doing as was intended.

9dd81ae53d Use settings for DAC AGC, cpeaker driver bias current (which is unused in rockbox), dither, and headphone bias current taken from c200v2 firmware. These should result in several mA power savings on all as3525, and probably an improvement on AS3525v2 as well as the c200v1 and e200v1. RMAA tests on the e200v1, clipv1 and clipv2 show no measurable difference in output when driving a 16 ohm load.

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. ;)
