This change represents a name change only. There is currently an
effort to port AVRPROG to other platforms including Linux and Windows.
Since Atmel's programmer binary that's included within their AVR
Studio software is named AVRPROG.EXE on the Windows OS, there is the
chance for confusion if we keep calling this program AVRPROG as well.
Up until now the name hasn't really been a problem since there was no
chance to confuse 'avrprog' on Unix with Atmel's AVRPROG because
Atmel's tools only run on Windows. But with the Unix 'avrprog'
possibly being ported to Windows, I felt a name change was the best
way to avoid problems.
So - from this point forward, my FreeBSD Unix program formerly known
as AVRPROG will subsequently be known as AVRDUDE (AVR Downloader/UploaDEr).
This change also represents a time when the AVRDUDE sources move from
my own private repository to a public repository. This will give
other developers a chance to port AVRDUDE to other platforms and
extend its functionality to support additional programming hardware,
etc.
So goodbye AVRPROG, welcome AVRDUDE!

Fix setting of status LEDs under various write-fail conditions.
Add a flag to indicate that a memory type requires the device to
possibly be powered off and back on after a write to it. This is due
to a hardware problem on some Atmel devices, see:
http://www.atmel.com/atmel/acrobat/doc1280.pdf
Add greater verbosity to the part-display code when verbose>1 to
display avrprog's encoding of the defined programming instructions.
This is primarily for debugging purposes.
Part updates:
* add the AT90S4414 part
* add fuse and lock bit access instructions for the AT90S1200,
AT90S4434, and AT90S8515.
* add the pwroff_after_write flag to the fuse bits for the AT90S2333
and AT90S4433 parts

serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.
This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file. Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips. I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts. It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.

Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands. Thus,
these routines won't work for the ATMega103, for example.
Add support for sending raw command bytes via the interactive terminal
interface. This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not. Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.
Add in comments, an experimental instruction format in the
configuration file. If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.

Due to the bank addressing required, interactive update of the flash

Additionally, display a revision timestamp along with the version

First pass at providing feedback via the optionally connected leds. I

Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins. This is important when programming the target
in-system.
Totally change the way the pin definitions are defined. Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination. A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.

prompted.
avr.c avr.h fileio.c term.c :
Change the avrpart data structure so that the typedef AVRMEM is
used as an index into an array for the sizes of the memory types
and also for pointers to buffers that represent the chip data for
that memory type. This removes a lot of conditional code of the
form:
switch (memtype) {
case AVR_FLASH :
...
}
Also, re-code avr_read_byte() and avr_write_byte() to properly
handle the flash memory type without having to tell them whether
they should program the high byte or the low byte - figure that
out from the address itself. For flash memory type, these
routines now take the actual byte address instead of the word
address. This _greatly_ simplifies many otherwise simple
operations, such a reading or writing a range of memory, by not
having to worry about whether the address starts on an odd byte
or an even byte.

When reading input data from a file, remember how many bytes were read

Don't complain when an input file size is smaller than the memory size
we are programming. This is normal.
