Brian S. Dean fb233af934 This is a jajor re-write of the programming algorithms. The Atmel
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.

Brian S. Dean 3bae0d8d14 First cut at supporting the ATmega 103 which uses bank addressing and
has a 128K flash.

Due to the bank addressing required, interactive update of the flash
is not supported, though the eeprom can be updated interactively.
Both memories can be programmed via non-interactive mode.

Intel Hex Record type '04' is now generated as required for outputing
memory contents that go beyond 64K.

Update copyrights.

Brian S. Dean 9003ed1183 Make the pin definitions configurable based on entries in a config
file.  This makes supporting other programmers much easier.

Rename AVRprog.pdf to avrprog.pdf.

Brian S. Dean 26223415e6 Add a -V option to display the version information about each
component module.  This is intended for support purposes, so that I
can tell unambiguously what version a binary out in the field is.

Additionally, display a revision timestamp along with the version
number.  This also is intended for aiding in support and is the Unix
time of the latest component module.  Having this, should allow me to
do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.

Brian S. Dean 34faf25814 Return the maximum address (+1) written as opposed to the actual number of
bytes written.  The presence of an Intel Hex address record can cause
these two number to be different; but the callers of this routine need
the former.

fileio.c: Properly handle all the Intel Hex record types that I can
          find information about.

Brian S. Dean 209f979c7f Makefile : use gzip -f for man page installation so that we don't get
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.

Brian S. Dean c06319e33c Return error codes instead of exiting, thus making sure that we exit
only via main() so that the exitspecs are properly applied.

When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.

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

Brian S. Dean 3d43a61bcc Correct checksum calculation; failure to account for the value of the
record type was causing non-zero record types to be calculated
incorrectly.

Brian S. Dean 4265bfa150 The program was getting too large for a single file. Split it up into
more modular pieces.

Also, accept command abbreviations as long as they are not ambiguous.
