Indent the asm constraints at the same level than instructions
Also add a trick to reduce the number of instructions outputted by gcc
in the commented C version of the loop
The difference between C and asm is now 1 instruction

This fixes the error introduced in r25989, where it would release the
DMA engine when uninitializing recording.
The real bug has been fixed instead (in pitch_detector)
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26003 a1c6a512-1295-4272-9138-f99709370657
also avoid disabling completely the DMA engine in pitch_detector

The OF does this and while we don't have the documentation to be sure I think it's highly likely this is a low power mode referred to in one of the product "briefs".

This seems to make switching the uSD card to high speed timing much more reliable.

When the rest of the code is confirmed to work properly without CPU
frequency changes, it will be possible to reliabily test set_cpu_frequency()

Get a bit more battery life (between 30 minutes and 2 hours)
as3525v2: only enabled in bootloader, we need a new binary release anwyway
as3525v1: enabled in rockbox.sansa as well, so we can continue using the
current bootloaders

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

Some SD cards were having problems switching to 4 Bit widebus and this solution appears to remedy that.
Thanks to Luca_S!

These INT's shouldn't be unmasked until the transfer is just about to happen.

all as3525v2 use ADC_CHG_IN because ADC_BVDD is way too high when charging
Fuzev2 now displays battery icon correctly when charging

Change SD_SELECT/DESELECT_CARD commands to MCI_NO_RESP as we don't need a response here.
Renumber some command errors.

delays after modifying the registers seems not to be needed
moving RAM operation (cpu_frequency variable) before modifying the
register also seems to help
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25754 a1c6a512-1295-4272-9138-f99709370657
We do not need any delay after modifying it in system_init(), so the
same applies in set_cpu_frequency()

- remove udelay(1) and use the previous busy loop : the delay was too
long for proper hold detection
- remove the 2nd delay (unneeded)

fix audio stuttering on fuzev2

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.

Revive the delay removed by r25636 (and make it longer so it works when
boosted)
Also read GPIOA pins 7 & 6 in one load
