This platform has been marked as orphan since June of 2016 and should
have been removed some time ago.  Do so now.

-By Thomas.Lange@corelatus.se 2004-Oct-05
-----------------------------------------
-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. CONFIG_SYS_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...
