JFFS2 speed enhancements:
- repair header CRC calculation in jffs2_1pass.c
- add eraseblock size to the partition information to skip empty
eraseblocks if we find more then 4k of free space.
- The JFFS2 scanner is now fast enough to remove the spinning wheel
so #ifdef-ed out.
- add watchdog calls in long running loops

|
|
* All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h
|
|
* are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
|
|
* Those are used for drivers on multiple OS', so some thing may seem
|
|
* unnecessary complicated on Linux. Please do not try to 'clean up'
|
|
* them without VERY good reasons, because this will make it more
|
|
* difficult to keep the Linux driver in synchronisation with the
|
|
* other versions.
