source: soft/giet_vm/giet_drivers/mmc_driver.h @ 482

Last change on this file since 482 was 481, checked in by alain, 10 years ago

1) The NIC, IOC, DMA and HBA drivers have been adapted to support the new _v2p_translate() function prototype (returns void).
2) The _mmc_inval() and _mmc_sync() functions does not use anymore the hard lock in the MMC, but use a soft spin_lock.
3) The NIC driver does not use anymore the GIET_NIC_BUFSIZE, GIET_NIC_NBUFS, and GIET_NIC_TIMEOUT parameters (removed from giet_config.h file).
4) The NIC driver registers map has been modified to support 64 bytes buffer descriptors for chained buffers.
