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.

* 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.

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.

Add an argument int_prio to TIMER_START() macro because SH7034 needs it

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.

Those two drivers were so similar, merging them is worth a few more #ifdefs.

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)
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21330 a1c6a512-1295-4272-9138-f99709370657
The LCD driver is unified and lcd_send_command now takes 2 arguments : the command and its argument.
If there is no argument, it's set to 0 and a NOP command is issued
If there is more than one argument (set X/Y address), the 2nd argument is sent as a 2nd command, and a NOP command is issued after it.
Benefit : c200v2 transfers the command and the argument in one 16 bits transfer
Performance should not be affected since commands without argument are only used in lcd_init() and lcd_enable()
lcd_send_data() now transfers whole lines (or columns) instead of single pixels
yuv is disabled for c200v2 for now
Some buttons can be read, including left button (bit 6 of DBOP_DIN), but for some reason they have no effect in rockbox: to be investigated
