This still doesn't solve the problem of the cards being overclocked at 62MHz but we can mitigate this a bit by switching to HS timings.

of 400 khz Ident freq. Also misc formatting changes.
Displaying the 400 khz ident frequency for the SD and uSD cards was not really
useful information. This change displays the MCICLK frequency that we are
running the cards at. The page now displays 0MHz until a card access and then
will displays the set frequency and the actual frequency. The uSD display is
now only displayed for those players with a uSD

The blue bars I previously had with this way are fixed by blocking DBOP output while reading buttons from GPIO.
We reached the maximum fps even at unboosted now (100.0 fps at lcd_update(), DBOP can't do more). Optimisation to YUV stuff is still possible though.
The e200v2 scrollwheel is very improved due to the this and the previous speedup since the chance of getting the wheel read blocked is greatly decreased with faster updates.

Unaligned (to 4byte boundary) and odd (where the amount of data is not an integer multiple of 32bit) are still supported. Even those still have a speedup of >2.

Nothing should change, since the value of transfer didn't change in the == case, but it saves executing this case at least.

If µSD init fails, rockbox will panic and give an error number
Use a maximal delay of 1 second for µSD (and internal storage) init, as
specified in the SD Specification 2.00

* Ingenic SD driver: cleanup DMA part a bit (not working yet)
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21606 a1c6a512-1295-4272-9138-f99709370657
ingenic SD driver needs more cleanup so it still doesn't use the common code
correct a comment in hotswap.c: card_extract_bits assume most significant word of register first (so, use this order)
fix debug menu which used MMC specific commands / bits positions in csd/cid
move the default block size of 512 into sd.h
move the mantissa & exponent table into a single file (sd.c) to reduce binsize. we don't need to export it anymore anyway
TODO : ingenic cleanup (will happen soon so building sd.c is not conditional)
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21601 a1c6a512-1295-4272-9138-f99709370657
Put specific members under #ifdef (CONFIG_STORAGE & STORAGE_xx) (2 members for SD and 1 for MMC)
Fix a typo: tsac doesn't exist and must be read taac
Move card_get_info functions declaration inside hotswap.h to remove mutual inclusion of ata_mmc.h and hotswap.h
Move static const data structures from SD drivers into sd.h (sd_exponent and sd_mantissa)
Fix sd_command prototypes in SD drivers (card registers are unsigned long)
Fix speed calculation in Sansa AMS driver (PP SD driver needs to be checked)
Move ata-sd-target.h to sd-pp-target.h to reflect the PP specifity. Now it only contains declaration of microsd_int()
Remove unused ata-sd-target.h for injenic
TODO:
- check if CSD register bits are extracted correctly in PP driver
- correctly define read_timeout and write_timeout unit for MMC & SD, and use timeouts in Sansa AMS driver

The input to the ADC is now set to CVDD inside the while loop. If the input gets changed while waiting for the voltage to be read it will now be reset to CVDD before the next read is attempted.
