-- Revision 1.21  2005/10/24 09:54:55  haraldkipp
-- New i2C bit banging driver.
-- New Xicor RTC driver.
-- New Cypress programmable clock driver.
--
-- Revision 1.20  2005/10/04 05:48:11  hwmaier
-- Added CAN driver for AT90CAN128
--
-- Revision 1.19  2005/07/26 15:41:06  haraldkipp
-- All target dependent code is has been moved to a new library named
-- libnutarch. Each platform got its own script.
--
-- Revision 1.18  2005/05/27 13:51:07  olereinhardt
-- Added new Display sizes for hd44780 and hd44780_bus
-- Ports used for display connection still need's to be added.
--
-- Revision 1.17  2005/04/05 17:44:56  haraldkipp
-- Made stack space configurable.
--
-- Revision 1.16  2005/02/21 00:56:59  hwmaier
-- New CAN int vectors ivect35.c and ivect36 added, removed "makedefs" entry for RTL_IRQ_RISING_EDGE.
--
-- Revision 1.15  2005/02/19 22:47:54  hwmaier
-- no message
--
-- Revision 1.14  2005/02/07 19:05:25  haraldkipp
-- ATmega 103 compile errors fixed
--
-- Revision 1.13  2005/02/02 19:46:53  haraldkipp
-- Port configuration was completely broken, because no AVRPORT values
-- had been defined for the preprocessor. To fix this without modifying
-- too many sourcefiles we change the name of AVR port config file and
-- include this new file in the old avr.h.
--
-- Revision 1.12  2005/01/22 19:22:42  haraldkipp
-- Changed AVR port configuration names from PORTx to AVRPORTx.
-- Removed uartspi devices.
--
-- Revision 1.11  2004/12/17 15:31:28  haraldkipp
-- Support of rising edge interrupts for hardware w/o inverter gate.
-- Fixed compilation issue for hardware with RTL reset port.
-- Thanks to FOCUS Software Engineering Pty Ltd.
--
-- Revision 1.10  2004/11/24 14:48:34  haraldkipp
-- crt/crt.nut
--
-- Revision 1.9  2004/10/03 18:39:12  haraldkipp
-- GBA debug output on screen
--
-- Revision 1.8  2004/09/25 15:43:54  drsung
-- Light change for separate interrupt stack. Now it depends also
-- on macro HW_MCU_AVR.
--
-- Revision 1.7  2004/09/22 08:21:43  haraldkipp
-- No ATmega103 support for LAN91C111. Is there any hardware?
-- List of devices sorted by platform.
-- Separate IRQ stack for AVR is configurable.
-- Configurable ports for digital I/O shift register.
-- Configurable handshake ports for AVR USART.
--
-- Revision 1.6  2004/09/07 19:11:15  haraldkipp
-- Simplified IRQ handling to get it done for EB40A
--
-- Revision 1.5  2004/09/01 14:04:57  haraldkipp
-- Added UART handshake and EEPROM emulation port bits
--
-- Revision 1.4  2004/08/18 16:05:38  haraldkipp
-- Use consistent directory structure
--
-- Revision 1.3  2004/08/18 13:46:09  haraldkipp
-- Fine with avr-gcc
--
-- Revision 1.2  2004/08/03 15:09:31  haraldkipp
-- Another change of everything
--
-- Revision 1.1  2004/06/07 16:35:53  haraldkipp
-- First release
