Adjust SD timeouts accordingly.
Adjust code in debug-as3525.c to display correct frequencies on system/debug/View disk info page.

Internal cards are v1 sd cards so no need to include this code for the clip.
Move transition from STBY -> TRAN-> STBY states inside the if(sd_v2) conditional check for HS switch as it's not needed for non HS cards.

If a card is reinitialized now the ident frequency is used instead of the bypass frequency during the identification phase.
Added comments throughout sd_init_card() to help follow init process and highlight indent stage.

Reimplement voltage scaling on AMS Sansas at 1.10v during unboosted operation to improve runtimes. The voltage is now also boosted during disk access if a µSD is present. This prevents the µSD problems we saw on the last implementation.

Remove useless E200V2 || FUZE || C200V2 : all those models have
MULTIDRIVE and/or HOTSWAP defined and have no specific difference.
Correct some comments
Remove HAVE_MULTIDRIVE within HAVE_HOTSWAP since HOTSWAP imply MULTIDRIVE
Change HOTSWAP to MULTIDRIVE where needed
Use NUM_DRIVES in sd_num_drives()

We are unable to successfully put the pl180 controller into 4 bit mode so we should not put the cards into widebus mode for now.
The blocklength is hardcoded to 512 in sd.c and BLOCKLEN defaults to 512 so this command is not needed.
It appears the internal SD card is not HS capable but sending it the HS switch command does not seem to hinder it's init process.
Assume all SD_V2 cards are HS capable and send them the HS switch command.
If View disk info shows 50.0 MBit/s the card has HS timings.

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.

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

The maximum number of errors is 10 (arbitrary)
A recovery mechanism is not in place (yet) but could be implemented in the future

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

This was only used for data transfers, now use it also for card data
transfers in sd_select_bank, to save runtime alignement and stack usage.
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21564 a1c6a512-1295-4272-9138-f99709370657
Put the card data sent by DMA aligned on cache line size, and in uncached memory
Since sd_select_bank() is not used very often, still allocate the DMA buffer on the stack.

Don't read the buttons from GPIOC but from DBOP_DIN (all directional buttons + select)
Still missing hold, rec, volume up and volume down
Read microsd
Tuner is a si4700 but seems to suffer from the same problem than e200v2
Sound works
TODO: missing buttons, lcd yuv, test lcd performance (the c200v1 lcd performance has decreased since r21321 : needs to be investigated)

Those are the recommended maximal timeouts in §4.6.2
Despite that, some people still experiment problems with the SD driver since MMU and data cache were enabled

- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)
Before reporting any problem, please check your filesystem or format your player from the OF

Fixes various storage related problems like stuttering audio, md5sum and test disk failure and Sansa Fuze's backdrop corruption by using aligned buffers. There's a speed penalty but stability has more priority.
