----------------------------------------
DbAu1xx0 are development boards from AMD containing
an Alchemy AU1xx0 series cpu with mips32 core.
Existing cpu:s are Au1000, Au1100, Au1500 and Au1550
Limitations & comments
----------------------
Support was originally big endian only.
I have not tested, but several u-boot users report working
configurations in little endian mode.
I named the board dbau1x00, to allow
support for all three development boards
( dbau1000, dbau1100 and dbau1500 ).
Now there is a new board called dbau1550 also, which
should be supported RSN.
I only have a dbau1000, so my 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 delivered with board.
NOTE! When you switch between the two boot flashes, the
base addresses will be swapped.
Have this in mind when you compile u-boot. TEXT_BASE has
to match the address where u-boot is located when you
actually launch.
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 and running cpu in big endian mode!!!!
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...

* 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
* 29-Jul-99 Added Full duplex support MKW
* 06-Aug-99 Changed names for Mal CR reg MKW
* 23-Aug-99 Turned off SYE when running at 10Mbs MKW
* 24-Aug-99 Marked descriptor empty after call_xlc MKW
* 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG

* - Receive buffer descriptor ring is used to send buffers
* to the user
* - Info print about send/received/handled packet number if
* INFO_405_ENET is set
* 17-Apr-01 stefan.roese@esd-electronics.com
* - MAL reset in "eth_halt" included
* - Enet speed and duplex output now in one line
* 08-May-01 stefan.roese@esd-electronics.com

* - ported from 405gp_enet.c to utilized upto 4 EMAC ports
* in the 440GX. This port should work with the 440GP
* (2 EMACs) also
* 15-Aug-05 sr@denx.de
* - merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
now handling all 4xx cpu's.
