464ab40e39 Revert "atusb/fw/usb/: enable MCU reset on USB bus reset after config selection" 
This reverts commit 9b2696b848.

With this patch ATUSB resets constantly when I use it in QEMU with USB
poassthrough.

88e2bde7d6 atusb/fw/usb/: fix incorrect code point for USB_CLASS_PER_INTERFACE 
The code of USB_CLASS_PER_INTERFACE is 0 and not 0xfe.
USB_CLASS_APP_SPEC is 0xfe. Also corrected the use in dfu.c

7fd9044d94 atusb/fw/: add SPI block reception 
This decreases the retrieval time for a frame of 102 bytes from
660 us to 384 us, corresponding to a speed change from about
1.26 Mbps to 2.17 Mbps (102 bytes plus 2 bytes overhead).

b73d5fc1af atusb/fw/mac.c: remove queued_rx; buffer frames in the MCU instead 
queued_rx held a frame in the transceiver's receive buffer until we could
transfer it. This may cause frame loss if a new reception begins.

We now retrieve frames from the transceiver immediately and buffer them
in the MCU.

9b2696b848 atusb/fw/usb/: enable MCU reset on USB bus reset after config selection 
This way the host can reset the MCU if it's hung (for example, in the
panic loop) and we don't need to unplug-replug.

eeeb5599f8 atusb/fw/mac.c: reserved code 0 and added notification of TX completion 
- mac.c (queued_tx_ack, rx_done, handle_irq): on TX completion, send a
  a zero byte on EP 1
- mac.c (handle_irq): don't receive zero-sized frames (they're
  malformed anyway), so that size zero can be used to signal TX
  completion

862b554e2d libatrf: added HardMAC functions 
This function set isn't really usable for real communication. Its main
purpose is to help with testing the firmware.

- tools/lib/driver.h (struct atrf_driver): added driver functions for
  HardMAC access
- tools/include/atrf.h (atrf_rx_mode, atrf_rx, atrf_tx),
  tools/lib/atrf.c: functions to enable/disable HardMAC mode and to
  send/receive frames

- mac.h, mac.c: basic "HardMAC" procedure
- board_app.c (INT0_vect): call MAC-specific interrupt handler if
  provided
- Makefile (OBJS): added mac.o

42483d67b4 atusb/fw/: added improved support for interrupt synchronization 
At an interrupt barrier, the host must be able to ensure that no
interrupt generated before reaching the barrier is still pending and
will be delivered after crossing the barrier.

For this, we introduce the following concept:

- interrupts have a serial number. This number is sent to the host
  on EP 1 (currently bulk) to signal the interrupt, instead of the
  zero byte we used previously.

- the new request ATUSB_SPI_WRITE2_SYNC returns the interrupt
  serial number from after the register write (the register write
  itself is the interrupt barrier).

- the host can now check if the serial indicated from bulk and the
  serial from ATUSB_SPI_WRITE2_SYNC are the same. If yes, interrupts
  are synchronized. If not, it has to wait for the interrupt to be
  signaled on EP 1.

We should also consider the case that the interrupt serial has gotten
ahead of ATUSB_SPI_WRITE2_SYNC. But that seems to happen rarely. In
any case, it's something for the host driver to worry about, not for
the firmware.

- board.h (irq_serial), board_app.c (irq_serial, INT0_vect): count
  the interrupt serial number and return it when signaling the
  interrupt
- include/atusb/ep0.h (ATUSB_SPI_WRITE2_SYNC), ep0.c (my_setup):
  new request ATUSB_SPI_WRITE2_SYNC that does a register write, then
  returns the interrupt serial
