* [MMC] pxamci: fix data timeout calculationRussell King2006-04-241-6/+4
| | | | | | | | | | | The MMC layer gives us two parts for the timeout calculation - a fixed timeout in nanoseconds, and a card clock-speed dependent part. The PXA MMC hardware allows for a timeout based on the fixed host clock speed only. This resulted in some cards being given a short timeout, and therefore failing to work.

* [ARM] 3457/1: i.MX: SD/MMC support for i.MX/MX1Pavel Pisa2006-04-024-0/+1174
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Pavel Pisa This patch adds support of i.MX/MX1 SD/MMC controller. It has been significantly redesigned from the original Sascha Hauer's version to support scatter-gather DMA, to conform to latest Pierre Ossman's and Russell King's MMC-SD Linux 2.6.x infrastructure. The handling of all events has been moved to the softirq context and is designed with no busy-looping in mind. Unfortunately some controller bugs has to be overcome by limited looping about 2-20 usec but these are observed only for initial card recognition phase. There are still some missing/missed IRQs problems under heavy load. Help of somebody with access to the full SDHC design information is probably necessary. Regenerated against 2.6.16-git-060402 to solve clash with other patches.

| | | | | | | | | | | | | Patch from Andrew Victor This patch adds support for the MMC/SD card interface on the Atmel AT91RM9200 processor.

* | [PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig2006-01-081-19/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

* [MMC] Set correct capacity for 1024-byte block cardsRussell King2005-12-221-5/+9
| | | | | | | | | | | | | | | | | | | We were passing set_capacity() the capacity we calculated in terms of the number of blocks on the card, which happened to be the right units for 512-byte block cards. However, with 1024-byte block cards, we end up setting the capacity to half the number of blocks. Fix this by shifting by the appropriate amount. Thanks to Todd Blumer for pointing this out. Use get_capacity() to report the card capacity, rather than recalculating it from the CSD information. Finally, use our chosen IO block size for the SET_BLOCKLEN command rather than the CSD read block size. Currently these are equivalent, but will not be in the future.
