| | | | | | | | | interface for "reading memory" akin to the bus_space(9) API. The already existing multi interface is used for "reading FIFOs". The technical difference is that one always reads from the same address (FIFO) while the other increments the address while reading (memory). ok kettenis@

| | | | | | | | | | | | support ADMA2. The older SDMA mode has too many limitations to be really usable. Gives us only moderate speed improvements, bus reduces the CPU load considerably. We will reap the full benefits once we implement wider bus widths and high speed modes. There is a remining issue with simultanious use of eMMC and external SD card on (some) Intel Bay Trail hardware. Still under investigation. ok patrick@, stsp@, deraadt@

* Fixed config_pending calls in sdmmc(4)uwe2011-11-101-1/+2
| | | | | | | | Root on SD/MMC card did not work reliably because the config_pending state was cleared too early. This change will clear config_pending only after the card discovery has actually completed once. ok deraadt@ drahn@

| | | | | | | | | | | | | | 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.
