Linux Operating System Source Code: IBM Patches

 
edb7211 flash driver enhancements
Description:
The patch enhances edb7211_flash.c with flash write support, buffered write support and multiple banks and sector sizes support.
Developer:
Sreekrishnan V
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.
