* Ingenic SD driver: cleanup DMA part a bit (not working yet)

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

Inline the 2 uses, and use a preprocessor sanity check for identification frequency

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.

the AMS sansas, which solves the ">2GB problem" (the problem that we could not
access data past 1GB on devices having more than 2GB internal storage).

Retry blocks transfer if a problem happened
Remove unneeded blocking API from DMA code

* Adds a callback to be called on end of transfer
* Add a function to disable a channel
* Services the 2 channels if both are active in the isr
SD driver: panics on error

Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

- Make write_sectors() function fail.
- Disable interrupts while transferring data and do not yield(), so we are sure the FIFO is not overflowed
Note this solution is only temporary since it's not friendly to other threads and confuse kernel tick precision
This will be reverted when we will be using DMA to access the SD card, but for now it permits further development
- PL180: Rename the MMC_* registers into MCI_*, to not make people believe it is a MMC only controller
- Supports non aligned destination buffers when reading
- Correct the timeout units which were lamely copied from ata-sd-pp.c and were in milliseconds (note that the timeouts are disabled now)
- Higher a bit the stack size
- Use the full initialization procedure in the bootloader and the loaded firmware
- Use the CCU_IO register only when a SD slot is present
- Put some panicf() around to catch problems
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19122 a1c6a512-1295-4272-9138-f99709370657
Implement some of the new functions
Use as3514 rtc
Add AS3525 case in rolo.c
Copy card_get_info_target() from ata-sd-pp.c , and use the correct 32bits words order
