Status:
Available from IBM |

Release Included:
2.4.2-rmk1-bluemug7 |
|
Relevant Architectures:
ARM |

Notes:
Accesses to flash are buffered using a sector buffer. Writes and
reads go through the buffer, so device accesses occurs less frequently.
flash-write entry point has been almost completely re-written. Requests
can span sector boundaries. The code is aware of the 2 different
sector sizes (16k and 128k). The banks have been made virtually
contiguous. (ep7211.h). The file-system should be able to start
anywhere in a bank rather than at the top of a bank, and should
also be able to span banks. |
