Now it's possible to have more than one instance of a given file
system. For example, one could use more that one ROM file system
in different physical locations (a possible configuration is
internal Flash and external serial memories). This mechanism is
currently implemented only in the device manager (devman.c),
actual instance implementation require per-FS support (to be
implemented later).
- enable file creation, reading, writing on mbed for the built-in filesystem
- implementation currently lacks support for directory listings, this will be
added when mbed implementation details are available.
Note: this should work with other ARM arm ports that are connected to a JTAG
debugger that implements semihosting, though I have not tested it.
