Details:
Recently, Atmel has discontinued their serial-based AVRISP programmer, and
now sell the AVRISP mkII, which is basically identical, except the serial
interface has been replaced with a USB interface.
This patch adds support for the AVRISP mkII.
The command format is identical to the existing STK500v2 support with one
exception: the range of supported SCK values is different. Thus, the patch
adds support for this new range of SCK values. In order to use a AVRISP mkII
programmer, simply specify STK500v2 as the programmer, and use the "-P usb"
option to indicate that it is connected via USB.
A few modifications were necessary to usb_libusb.c since the AVRISP mkII
does not encapsulate its frames in the same format as the jtagmkII. Instead,
it does not encapsulate frames at all, and just relies on the USB packet
boundaries to indicate the frame boundaries. A short packet must always
terminate a command or response. This required adding a new type of recv
command to usb_libusb.c.
