----------------------------------------
DbAu1000 is a development board from AMD containing
an Alchemy AU1000 with mips32 core.
Limitations & comments
----------------------
I assume that you set board to BIG endian!
Little endian not tested, most probably broken.
I named the board dbau1x00, to allow
support for all three development boards
some day ( dbau1000, dbau1100 and dbau1500 ).
I only have a dbau1000, so all testing is limited
to this board!
The board has two different flash banks, that can
be selected via dip switch. This makes it possible
to test new bootloaders without thrashing the YAMON
boot loader deliviered with board.
Ethernet only supported for mac0.
Pcmcia only supported for slot 0, only 3.3V.
Pcmcia IDE tested with Sandisk Compact Flash and
IBM microdrive.
###################################
######## NOTE!!!!!! #########
###################################
If you partition a disk on another system (e.g. laptop),
all bytes will be swapped on 16bit level when using
PCMCIA!!!!
This is probably due to an error in Au1000 chip.
Solution:
a) Boot via network and partition disk directly from
dbau1x00. The endian will then be correct.
b) Partition disk on "laptop" and fill it with all files
you need. Then write a simple program that endian swaps
whole disk,
Example:
Original "laptop" byte order:
B0 B1 B2 B3 B4 B5 B6 B7 B8 B9...
Dbau1000 byte order will then be:
B1 B0 B3 B2 B5 B4 B7 B6 B9 B8...

The config option CONFIG_SILENT_CONSOLE can be used to quiet messages
on the console. If the option has been enabled, the output can be
silenced by setting the environment variable "silent". The variable
is latched into the global data at an early stage in the boot process
so deleting it with "setenv" will not take effect until the system is
restarted.
The following actions are taken if "silent" is set at boot time:
- Until the console devices have been initialized, output has to be
suppressed by testing for the flag "GD_FLG_SILENT" in "gd->flags".
Currently only the messages for the TRAB board are handled in this
way.
- When the console devices have been initialized, "stdout" and
"stderr" are set to "nulldev", so subsequent messages are
suppressed automatically. Make sure to enable "nulldev" by
#defining CFG_DEVICE_NULLDEV in your board config file.
- When booting a linux kernel, the "bootargs" are fixed up so that
the argument "console=" will be in the command line, no matter how
it was set in "bootargs" before.
