Message:

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.
