for CCID (card reader operation) not, it is basically the Atmel
reference code merged with my DFU loader work and configured for the
SIMtrace hardware.

However, this is a completely different code base than what I used for
the old/current SIMtrace firmware.  At that point I simply recycled code
that I had written for openOCD many years earlier, when AFAIK there was
no at91lib from atmel that could be used.

So the 'simple' approach would be to not merge them yet, but have a CCID
+ phone-side firmware based on at91lib/at91work, but keep the old
openpcd derived firmware for tracing.  Switching the modes would then
require a firmware download.

As soon as somebody finds time, the two firmwares could be merged, but
my focus would be to have something that can do MITM at all, rather than
all features in one firmware image.

I fear you have to extend the respective CCID driver (libccid in the case
of Linux and AFAIK also MacOS).  I'm not aware of any standard interface
towards application programs to use this.  It's only standardized on the
USB side.
