2007-03-18Support the PXA27x SD/SDIO/MMC controller on ZaurusUwe Stuehler
We use the suggested workaround for the problem E40 in the PXA27x errata sheet. Unfortunately this limits the bus speed to 9.75Mhz.
2007-01-31Workaround for the problem where the SD card reader stops responding afterClaudio Jeker
a card is ejected. Problem identified and patch provided by Matthew R. Dempsky < mrd at alkemio dot org >: > According to the Simplified SD Host Controller spec, this change > shouldn't affect anything. All of the bits in the Software Reset > register are labeled as ignoring 0-bit writes, and yet somehow it > changes behavior. This seems to reliably fix the problems seen on many X40 laptops. Tested by many, OK beck@, "should be good to go" henning@

2006-07-30o Change sdhc_soft_reset() to pass the bits we want to reset and waitFederico G. Schwindt
until all bits are cleared. o Change sdhc_host_reset() to use the above function and use RESET_ALL. This avoid timeouts on TI controllers when initializing the controller but does not fix the command timeouts. uwe@ ok.

2006-07-18First and foremost, avoid an obious race between two or more processesUwe Stuehler
trying to get MMC commands through to the SD/MMC host controller via the emulated SCSI layer. This is achieved by ensuring exclusive access to the host controller for one process during any MMC command and during a sequence of commands at the sdmmc(4) layer. While at it, the command processing thread has been moved to sdmmc(4), so as to simplify the implementation of future host controller drivers. This should also pave the way for further cleanup of the code and for new drivers. Minor cleanups are included in this commit, as well.

correctly. uwe@ ok.

2006-06-29- Assign RCAs beginning at 1 since 0 is used to deselect all cards.Uwe Stuehler
- Always set the "SDIO function 0" pointer to something, even if it is a memory-only card to avoid further special cases in SDIO drivers.
2006-06-29Oops! Clear the "function 0" pointer when the card goes away.Uwe Stuehler
2006-06-29Thanks to ian@ who experimented a lot with his TI PCI7621 SDHC, we knowUwe Stuehler
that the controller "kind-of" works, but it does not indicate completion of the host controller reset. Thus we cannot know whether the reset was successful or not, so don't return an error if the reset timed out.
