The Busware HUL v1.1 dongle is a product very similar
to the rzusb dongle but with the at86rf212 instead of
the at86rf230 transceiver.
Some code refactoring has been made in order to better
support multiple hardware targets. This includes:
The reset_rf functions are now in the board specific files.
The led functions are now in the board specific files.
The register read/write functions are moved from mac.c to the generic
board.c file as they are used by functions like reset_rf that are
not within the mac.c file. Also the subreg_read and subreg_write
functions were introduced for convenience.
The function to change state is now also in board.c.
The hardware types are moved into the atusb.h file (which is always
synchrornized with the linux atusb driver) because they are now used
by the driver to identify and configure the hardware.
Within the makefile a new target name is specified called: hulusb

This patch adds support for the rzusbstick for the atusb firmware.
More detailed information about this usb stick:
http://www.atmel.com/tools/rzusbstick.aspx
Original I have the rzraven kit:
http://www.atmel.com/tools/rzraven.aspx
Which comes with a special cable and avr dragon programmer. You need
some programmer and wires to the programmers pins. To lookup how to
connect the programmer to the rzusbstick pinout, see:
http://www.atmel.com/Images/doc8117.pdf
page 22 (schematics of the rzusbstick).
Difference between atusb and rzusbstick(rzusb) is mainly the at86rf231
vs at86rf230 one. The rzusb contains the at86rf230 which is a little bit
hard to deal with it (and has a huge errata inside the datasheet).
Nevertheless with small schanges the atusb firmware can run now on the
rzusb. The rzusb contains also a bigger mcu, so we can maybe cache more
pdus for receive handling.
To compile the rzusb firmware call:
make NAME=rzusb
this will generate the rzusb.bin
then call the programmer (in my case avrdude):
avrdude -P usb -c dragon_jtag -p usb1287 -U flash:w:rzusb.bin
NOTE: currently there is no chance (I suppose) to ensure that the atusb
receive the correct firmware, so don't try to flash the atusb with the
rzusb firmware! Also the vendor and product id is the same.
This currently a RFC, it's a quick hack and I think we should update
more the documentation to support the rzusb.

- board.c (board_init), board_app.h (timer_init), board_app.c
(timer_init): moved timer initialization from board_init to
new function timer_init
- atusb.c (main): call timer_init
reset_rf now resets all GPIOs to their default state. This way, we
can easily recover from an incomplete or incorrect use of ATUSB_GPIO.
- atusb.c (main), board.c (reset_rf): moved call to spi_init into
reset_rf
- board.c (reset_rf, board_init): moved GPIO setup to reset_rf
- board.c (reset_rf): set GPIOs to reset defaults
- board.h (gpio), board.c: read/modify/write all settings of GPIO
ports
- include/atusb/ep0.h (enum atspi_requests): added new request
ATUSB_GPIO
- ep0.c (my_setup): ATUSB_GPIO reads/reconfigures a GPIO port
- atusb.c (main): poll the 16 bit timer for overflows
- board.h (timer_poll, timer_read), (board.c (timer_h, timer_poll,
timer_read, board_init): added support for a free-running 48 bit timer
(16 bits in hardware, 32 bits in software)
- include/atusb/ep0.h (ATUSB_TIMER), ep0.c (my_setup): new request
ATUSB_TIMER to retrieve the value of the 8 MHz counter
- include/atusb/ep0.h (enum atspi_requests): describe what the groups
of requests do
- usb/usb.h (USB_LANGID_ENGLISH_US): added USB LANGID for US-English
- board.h (board_sernum), board.c (board_sernum, hex, get_sernum,
board_init): provide the board's serial number in "board_sernum"
(UTF-encoded)
- sernum.h (sernum_get_descr), sernum.c (sernum_get_descr): return
string descriptors for the serial number
- descr.c (device_descriptor), usb/dfu.c (device_descriptor):
set iSerialNumber if serial number is available
- atusb.c (main), usb/dfu.c (my_descr): call sernum_get_descr for
unknown descriptors
- Makefile (OBJS, BOOT_OBJS): added sernum.o
- board.c (board_init): disable the watchdog timer (tricky !)
- board.h (reset_cpu), board.c: enable the watchdog timer to cause a
CPU reset
- ep0.c (my_setup): uncommented and updated ATUSB_RESET handler
