This is necessary for support of block devices with >512 byte
blocks, such as most SPI flash parts.
- Enabled support of up to 4096 byte blocks
- Added support for heap-backed buffers using _FS_HEAPBUF
- Necessary to avoid stack overflows
- Avoids over-aggresive allocations of _MAX_SS
- Enabled _FS_TINY to further reduce memory footprint
- Haven't found a downside for this yet except for possible
thread contention
- Implicit MBR still allowed during mount
- maintains storage compatibility
- Not needed
- MBR utility is not exposed through the FAT filesystem,
so the only used partition was always the first. Omitting
the MBR is functionally equivalent
- Saves a few blocks on storage for MBR + offset
for FAT alignment
- Duplicated with MBRBlockDevice
- The implicit MBR actually prevents nesting a FAT filesystem
in the MBRBlockDevice
- Remove write set of functions
- Caused confusion with small benefit
- Trivial to add later
- Remove unused error codes
- Initial expirementation indicates most of these may not be useful
- Trivial to add later
- Removed bd_error_t
- Carries to additional type information, int already carries
sufficient connotation
- Trivial to add later
per @c1728p9, @sg-
- Fixing code formatting errors with astyle tool.
- Replaced use of TOOLCHAIN_xxx macros with compiler emitted macros.
- Added const to BlockDevice::get_xxx_size() member functions.
- Added documentation for FAT filesystem thread support.
- Added documentation for fat_filesystem_set_errno().
- Added documentation clarifying the reasons for errno/stat symbol definitions in retarget.h.
- Removed FAT filesystem from mbed 2 testing.
- Fixed FATMisc.h Copyright (c) 2016 year to 2017 as its a new file.
- Removed #ifndef NDEBUG from HeapBlockDevice.cpp.
- Removed unnecessary todo comment in retarget.cpp.
- renaming FATFileSystemSetErrno() fat_file_system_set_errno.
- changing FATFileSystem::format() to be mount fs internally in function, rather than expecting fs to be mounted.
- requested const char *filename change.
