FATFS and FreeRTOS again

Hi Sergio,

Congratulations.

Just a Note:
If you have planed to use SPI for other device and not using FATFS in multiple tasks simaltanously, then its sufficient to lock/unlock just SPI calls.

Aceesing the FATFS calls for writing to a SDcard from multiple tasks with mutex, decreses the card read/write speed in realtime.

Example:Writing a PCM Audio data @44.1Khz is not possible in realtime with SPI interface.

Prithwee.
