- cache.c
- The cache is not visible to the user. It should be flushed
- when any file is closed or changes are made to the filesystem.
-
- This cache implements a least-used-page replacement policy. This will
- distribute sectors evenly over the pages, so if less than the maximum
- pages are used at once, they should all eventually remain in the cache.
- This also has the benefit of throwing out old sectors, so as not to keep
- too many stale pages around.

- 2005-11-06 - Chishm
- * Added WAIT_CR modifications for NDS
-
- 2006-02-03 www.neoflash.com
- * Added SUPPORT_* defines, comment out any of the SUPPORT_* defines in disc_io.h to remove support
- for the given interface and stop code being linked to the binary
-
- * Added support for MK2 MMC interface
-
- * Added disc_Cache* functions
-
- 2006-02-05 - Chishm
- * Added Supercard SD support
-
- 2006-02-26 - Cytex
- * Added EFA2 support
-
- 2006-05-18 - Chishm
- * Rewritten for FATlib disc.c
-
- 2006-06-19 - Chishm
- * Changed read and write interface to accept a u32 instead of a u8 for the number of sectors
-
- 2006-07-11 - Chishm
- * Removed disc_Cache* functions, since there is now a proper unified cache
- * Removed SUPPORT_* defines
- * Rewrote device detection functions
- * First libfat release
-
- 2006-07-25 - Chishm
- * Changed IO_INTERFACEs to const

- The cache is not visible to the user. It should be flushed
- when any file is closed or changes are made to the filesystem.
-
- This cache implements a least-used-page replacement policy. This will
- distribute sectors evenly over the pages, so if less than the maximum
- pages are used at once, they should all eventually remain in the cache.
- This also has the benefit of throwing out old sectors, so as not to keep
- too many stale pages around.
