* Documentation updates * Documentation updates
0.1.2 2007-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr>
* Add dirent.h, opendir(), readdir(), closedir(), etc.
* Added 'ls' command to nsh
* Added C5471 watchdog driver
* Added support for the Neuros OSD / DM320
* Fixed another bug where free() is called from IDEL task.
Can't do this; the caller must be able to wait for access
to memory.
* Separated C5471 serial driver; a shareable part is
in drivers/. ; the C5471 specific part is in arch/C5471.
serial.h defines the interface.
* Fixed mq_receive() -- bad memcpy()
