0.1.0 2007-03-09  Gregory Nutt <spudmonkey@racsa.co.cr>

	* Initial Release
	* Support for Linux user mode simulation and TI
	  TMS320C5471 (Arm7) provided

0.1.1 2007-03-14  Gregory Nutt <spudmonkey@racsa.co.cr>

	* Corrected an error in interrupt level context switching
	  for C5471
	* Added fgets() and gets() logic; verified c5471 console read.
	* Corrected error in reading from the C5471 serial port:
          Improper use of semaphore can cause deadlock.
	* Fixed an error in the memory cleanup:  The idle task
	  cannot take sempahores (because it must always be ready
	  to run).
	* Tasks can now accept a configurable maximum number of
	  input parameters (argc)
	* _task_init() was divided into separate functions that
	  require fewer parameters.  This was necessary to keep
	  the stack usage down for the 8051/2 (which has only
	  256 bytes of stack).
	* Attempts to use C5471 console from interrupt handlers
	  can cause errors. Added a special path for this case.
	* Refuse calls to sem_wait and sem_trywait from interrupt
	  handlers.  This was happening because interrupt handlers
	  were calling printf-like functions.
	* Added strtok() and strtok_r()
	* Added a simple shell called nsh (see examples/nsh).
	* Platform support for 8052 is complete but not stable
	  when the timer interrupt is enabled.  Seems to be an
	  issue when SP enters indirect address space.
	* Documentation updates

0.1.2 2007-xx-xx  Gregory Nutt <spudmonkey@racsa.co.cr>

	* Add dirent.h, opendir(), readdir(), closedir(), etc.
	* Add strerror()
	* Added 'ls' command to nsh
	* Added C5471 watchdog driver
	* Added support for the Neuros OSD / DM320
	* Fixed another bug where free() is called from IDLE 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() and mq_send() -- bad memcpy()
	* Added a test for roundrobin scheduler.
