Changes since U-Boot 1.1.1:
======================================================================
+* Patch by Sascha Hauer, 28 Jun:
+ - add generic support for Motorola i.MX architecture
+ - add support for mx1ads, mx1fs2 and scb9328 boards
+
+* Patches by Marc Leeman, 23 Jul 2004:
+ - Add define for the PCI/Memory Buffer Configuration Register
+ - corrected comments in cpu/mpc824x/cpu_init.c
+
+* Add support for multiple serial interfaces
+ (for example to allow modem dial-in / dial-out)
+
* Patch by Stefan Roese, 15 Jul 2004:
cpu/ppc4xx/sdram.c rewritten now using get_ram_size()
* Fix NSCU config; add ethernet wakeup code.
-* Add link for preloader for Motorola Coldfire to RAEDME.m68k
+* Add link for preloader for Motorola Coldfire to README.m68k
* Patch by Michael Bendzick, 12 Jul 2004:
fix output formatting in drivers/cfi_flash.c

+The support for multiple serial interfaces as implemented is mainly
+intended to allow for modem dial-in / dial-out while still being able
+to use a serial console on a (different) serial port.
+
+At the moment, the ports must be split on a SMC and a SCC port on a
+8xx processor; other configurations are not (yet) supported.
+
+Support for hardware handshake has not been implemented yet (but is
+in the works).
+
+*) The default console depends on the keys pressed:
+ - SMC if keys not pressed (modem not enabled)
+ - SCC if keys pressed (modem enabled)
+
+*) The console can be switched to SCC by any of the following commands:
+
+ setenv stdout serial_scc
+ setenv stdin serial_scc
+ setenv stderr serial_scc
+
+*) The console can be switched to SMC by any of the following commands:
+
+ setenv stdout serial_smc
+ setenv stdin serial_smc
+ setenv stderr serial_smc
+
+*) If a file descriptor is set to "serial" then the current serial device
+will be used which, in turn, can be switched by above commands.
+
+*) The baudrate is the same for all serial devices. But it can be switched
+just after switching the console:
+
+ setenv sout serial_scc; setenv baudrate 38400
+
+After that press 'enter' at the SCC console. Note that baudrates <38400
+are not allowed on LWMON with watchdog enabled (see CFG_BAUDRATE_TABLE in
+include/configs/lwmon.h).
