The very basic functionality (paged flash read/write, erase, terminal
mode reads, fuse writes) works fine. There are still the following
issues right now:
. paged EEPROM write (i.e. through -U eeprom:w:...) only works on an
erased EEPROM
. byte-access flash and EEPROM writes (i.e. in terminal mode) fail
. documentation needs to be updated still

While Solaris' lex understands start conditions, they cannot be grouped,
so unfold the <strng> group.
All actions need braces, even if they only consist of a comment.
As the classic lex uses semi-static resource allocation, we need to bump
the resource limits quite a bit.

changes to butterfly.c include:
. do not exit for unsupported devices but return -1 from the init function
instead; that way the -F option can be used to continue anyway
. honor the -b option as arbitrary bootloaders could be implemented with
any baud rate, not just the fixed 19200 Bd used by the butterfly
. implement functionality to read the fuse and lock bits, and write the
(boot) lock bits, resp.
. fix the signature byte order

mkII.
The serial transport methods have been moved out into a record of
function pointers for that purpose, defaulting to the actual serial
connection that natively applies to the hosting system. Iff inside
the JTAG ICE mkII handler a port name starting with "usb" has been
detected, the record of function pointers is switched to USB.
Optionally, a serial number might be specified, so only the JTAG ICE
mkII matching the given serial number will be opened. The match is
done right-to-left, so only the least significant bytes of the serial
number need to be given.
In order to make the change as least intrusive to existing drivers as
possible, the entire naming scheme of the serial_foo() function entry
points has been maintained as access macros that encapsulate these
into the respective indirect function calls via serdev->foo().

When discarding a packet for being overly long, restart the state

It is unlikely in that case that preposterous amount of data would
ever arrive, so rather attempt to re-align the reading algorithm
(supposedly resulting in a timeout and retransmit).

. Implement the new EECRAddress field in the device descriptor that is
required by the 4.x firmware; make an uneducated guess about what
firmware requires what length of device descriptor -- perhaps Atmel
can be convinced to publish an official matrix for that.
. Specify EECR in the config file where required. Obviously, only
locations that differ from the 0x3c default are mentioned in the
XML files, so by now, this only affects the AT90CAN128 for us.
. After clarification with Atmel, EnablePageProgramming should really
default to 1, and only cleared if specified by an XML parameter. So
far, only the XML files for the ATmega256x and ATmega406 do specify
it at all, and they specify a 1, too.
. Drop the entire OCDEN fuse heuristic. If OCDEN is unprogrammed at
startup, issue a warning that single-byte EEPROM updates won't be
possible. Leave it to the user to program the fuse if desired.
That way, we won't run into any issue of prematurely wearing out the
hfuse EEPROM cell. Interestingly enough, this also solved the
problem of the target not restarting from scratch upon sign-off.

yesterday's changes (i.e. before rev. 1.10 of ser_posix.c), that is,
exit(1) in case of a timeout. Previously, the upper layers didn't see
the timeout at all.
Quite possible that some of these drivers could handle a timeout more
intelligently though. At least for the rather sophisticated STK500v2
protocol, I think it should be possible to retry the request.

Note that many consumers still read one byte at a time though.
This patch has once been submitted to me by Bernd Walter

Linux, too).

Walthinsen, as well as JTAG ICE mkII support (by me).
Erik's submission has been cleaned up a little bit, mostly to add his
name and the current year to the copyright of the new file, remove
trailing white space before importing the files, and fix the minor
syntax errors in his avrdude.conf.in additions (missing semicolons).
The JTAG ICE mkII support should be considered alpha to beta quality
at this point. Few things are still to be done, like defering the
hfuse (OCDEN) tweaks until they are really required. Also, for
reasons not yet known, the target MCU doesn't start to run after
signing off from the ICE, it needs a power-cycle first (at least on my
STK500).
Note that for the JTAG ICE, I did change a few things in the internal
API. Notably I made the serial receive timeout configurable by the
backends via an exported variable (done in both the Posix and the
Win32 implementation), and I made the serial_recv() function return a
-1 instead of bailing out with exit(1) upon encountering a receive
timeout (currently only done in the Posix implementation). Both
measures together allow me to receive a datastreem from the ICE at 115
kbps on a somewhat lossy PCI multi-UART card that occasionally drops a
character. The JTAG ICE mkII protocol has enough of safety layers to
allow recovering from these events, but the previous code wasn't
prepared for any kind of recovery. The Win32 change for this still
has to be done, and the traditional drivers need to be converted to
exit(1) upon encountering a timeout (as they're now getting a -1
returned they didn't see before in that case).
