eecec5bd59 SELECT_CARD command with zero RCA deselects all cards and so has no reply. 2008-10-11 17:30:02 +00:00

67d752c3d4 Give mmcsd driver a bit more information about card. It allows to reorganize 
log message in a way a bit more common for disk devices. Also it will allow
mmcsd driver to use MMC/SD specific commands when needed.

fa5f41d31c Add high capacity MMC cards support. 2008-10-09 20:09:56 +00:00

4871891e2c o Use seprate routines to decode cid and csd for sd and mmc cards. All they 
have in common right now is a memset.  This saves a parameter to
  these routines, as well as a level of indentation.
o Make mmc_get_bits a little clearer...  It really only works on 128-bit
  registers right now.

38c51cbe85 Define and use MMC_SECTOR_SIZE. 
Make mmc_get_media_size now return an off_t and remove now useless cast.

051bc8ead2 Make the media size return the block rather than the bytes on the device. 2008-09-29 18:55:45 +00:00

4e0efe35fa Explicitly set data to NULL rather than relying mmc_wait_for_cmd() to 
do it for us.  There may be commands we have to wait for that need to
set data.

dece39ab88 Minor style fixes from mav@ (with similar problems fixed where I noticed 
them):
	#define<tab>
	zero memory when we allocate it
	Put device name in error message.

128d0ff2c4 Conform to style(9) for return (foo); The files were a mix before.

6fdacf52be Convert all C++ comments to C style. There's lots of folks that don't 
like them and they don't add enough to be worth standing out.

e9bb9da34d The parameters to the MMCBR_ACQUIRE_HOST and MMCBR_RELEAES_HOST were 
the device in question, rather than the bus doing the requesting.  Fix
it so that it is the bus.

40fab6e7c7 Propigate read-only status of cards. Right now it is read only at 
device attach time.  We may need to read this more often in the
future, but for now simplicity of implementation wins.

8aaa15e202 The OCR register defines both acceptable voltage bits, as well as bits 
for other things.  Mask out the voltage only bits when returning the
Vdd mask for voltage computation.

2703cdbb1b Other busses on the system use the official capitalization for the

6634080bee MFp4: When querying the operating condition of SD cards (using the 
application specific SEND_OP_COND (CMD55 + ACMD41), go ahead and allow
100 tries.  This gives a timeout of a second rather than the ~100ms
the old style produces.

I've had one old 16MB SD card which needs the extra time.  I've now
had reports from the field that other cards need this too.

Originally done at BSDcan 2007 while waiting to give my embedding
madness minitalk.

14eced725c A careful reading of the disclaimer that is required to download the 
SD Simplified specification, as well as other SD and SDIO
implemenations I've examined, suggest this disclaimer may be required.
It is unclear to me exactly what the license would be for, or why it
might be required.  Err on the side of caution and include this
disclaimer so anybody deploying this code can judge for themselves.  I
have no further unformation about the details.

114b4164dd Preliminary MMC stack. This stack supports SD 1.0 cards only, but 
should be easily adapted to SD 2.0 (aka SDHC), SDIO, MMC and MMCplus
cards.  At the present time, there's only one bridge driver for the
ARM9 based Atmel AT91RM9200.
