* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
2000-11-01 Joel Sherrill <joel@OARcorp.com>
* startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
and libcsupport.h moved from libc to lib/include/rtems and
now must be referenced as <rtems/XXX.h>. Header file order
was cleaned up while doing this.
2000-10-27 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
Switch to GNU canonicalization.
2000-10-12 John S Gwynne <jgwynne@mrcday.com>
* start/start.c: Modified to support generation of ram_init.
* start/ram_init.ld, BSP/start/ram_init.sed: New files.
These changes enable RTEMS to automatically generate
the ram_init file used by gdb with the BDM patches. The 332 has
on-board chip select lines (for RAM and FLASH) that must be
configured before use of these peripherals. These patches parse
data from start.c where the chip select lines are configured in
the runtime executable and automatically generates the gdb
initialization file using the same settings. A great time saver.
A similar file, ram_init_FW (flash writable), is also generated
that the flash programming tool uses.
* start/Makefile.am: Modified to support above.
* CPU/sim.h: Modified to support above.
* startup/except_vect_332_ROM.S: Moved to start so it would not
be included in libbsp.a. Moving it to start ensures it is
available as a single object file.
* start/except_vect_332_ROM.S: Moved from startup.
* startup/linkcmds, startup/linkcmds_ROM: Fixes to the memory map
shown in the comments.
2000-09-29 Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
* startup/linkcmds: Added lines so DWARF debug information
would be available. Otherwise gdb complains that the offsets
for the debug info are incorrect and doesn't load the files.
2000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* clock/Makefile.am, console/Makefile.am, spurious/Makefile.am,
start/Makefile.am, startup/Makefile.am, timer/Makefile.am,
wrapup/Makefile.am: Include compile.am
2000-08-10 Joel Sherrill <joel@OARcorp.com>
* ChangeLog: New file.

Description: efi68k
============
CPU: MC68332 @20MHz
RAM: 256k max. (supports several configurations)
ROM: 512k (supports several configurations)
This general purpose controller has been designed by a group of
Internet subscribes to the mailing list "efi332" (an offshoot of the
"diy_efi" mailing list). Although efi332 was initially designed for
automotive research, it is a fairly generalized embedded controller
when used without the companion EFI I/O board, and is patterned much
after the the Motorola BCC. A 4x3 inch (approx.) printed circuit board
is available (about $14US). For complete information see
http://www.diy-efi.org
TODO:
=====
- integrate the interrupt driven stdin/stdout into RTEMS to (a) reduce
the interrupt priority and (2) to prevent it from blocking.
- add a timer driver for the tmtest set.

Description: efi68k
============
CPU: MC68HC000 @16MHz
RAM: 256k
ROM: 256k
Based upon a 16MHz 68HC000, efi332 is a minimally configured 4x6
inch single board computer. It includes the following major
components: (a) 256k SRAM (km681000l), (b) 256 EPROM (27C010),
(c) DP8570A (clock/timer/calendar), (d) MAX791 (cpu supervisory chip
with battery backup switch-over and watch dog timer), and
(e) NS16550DN (UART). The following interrupt functions have also been
incorporated: UART, TIMER, Watch Dog, and Low Line voltage (trips at
4.85V; enough time to save the cpu reg before reset is asserted on
power down).
The schematic for efi68k is freely available via e-mail. Send
"index diy_efi" to majordomo@coulomb.eng.ohio-state.edu. Retrieve the
files related to 68hc000-1.00 with the "get diy_efi <filename>"
command. efi68k does not have an available printed circuit board, but
can be wire-wrapped in about four days. Cost is about $100US.
TODO:
=====
- add the "tm27 vector" ... can we use a trap instruction?
- generate include/coverhd.c to perform the tmtest.
- the interrupt drive I/O should be integrated into the RTEMS.
- finish the ROM memory model.
- add separate interrupt stack (low priority).

detect when no battery is present at all. If normal
mode is selected and no battery is present, the
crystal will stop, but only if reset after
power-up. It would seem that after a power-up reset,
with no battery, the chip may automaticlly switch to
single supply mode which disables the low battery
detection circuit.) The following software tests
works for all permiatations of low batt, reset,
power-on reset, battery, no battery, battery on after
Vcc,.... *except* for battery switched on for the
first time before power up in which case the chip
will still be in single suppy mode till restarted (a
