-config FS_FAT
- bool "FAT file system"
- default n
- depends on !DISABLE_MOUNTPOINT
- ---help---
- Enable FAT filesystem support
-
-if FS_FAT
-config FAT_LCNAMES
- bool "FAT upper/lower names"
- default n
- ---help---
- Enable use of the NT-style upper/lower case 8.3
- file name support.
-
-config FAT_LFN
- bool "FAT long file names"
- default n
- ---help---
- Enable FAT long file names. NOTE: Microsoft claims
- patents on FAT long file name technology. Please read the
- disclaimer in the top-level COPYING file and only enable this
- feature if you understand these issues.
-
-config FAT_MAXFNAME
- int "FAT maximum file name size"
- depends on FAT_LFN
- ---help---
- If CONFIG_FAT_LFN is defined, then the default, maximum long file
- name is 255 bytes. This can eat up a lot of memory (especially stack
- space). If you are willing to live with some non-standard, short long
- file names, then define this value to be something more reasonable. A
- good choice would be the same value as selected for NAME_MAX which will
- limit the visibility of longer file names anyway.
-
-config FS_FATTIME
- bool "FAT timestamps"
- default n
- ---help---
- Support FAT date and time. NOTE: There is not
- much sense in supporting FAT date and time unless you have a
- hardware RTC or other way to get the time and date.
-
-config FAT_DMAMEMORY
- bool "DMA memory allocator"
- default n
- ---help---
- The FAT file system allocates two I/O buffers for data transfer, each
- are the size of one device sector. One of the buffers is allocated
- once for each FAT volume that is mounted; the other buffers are
- allocated each time a FAT file is opened.
-
- Some hardware, however, may require special DMA-capable memory in
- order to perform the the transfers. If FAT_DMAMEMORY is defined
- then the architecture-specific hardware must provide the funtions
- fat_dma_alloc() and fat_dma_free(): fat_dmalloc() will allocate
- DMA-capable memory of the specified size; fat_dmafree() is the
- corresponding function that will be called to free the DMA-capable
- memory.
