Limitations & comments

-I assume that you set board to BIG endian!
-Little endian not tested, most probably broken.
+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
-some day ( dbau1000, dbau1100 and dbau1500 ).
+( dbau1000, dbau1100 and dbau1500 ).
+Now there is a new board called dbau1550 also, which
+should be supported RSN.
-I only have a dbau1000, so all testing is limited
-to this board!
+I only have a dbau1000, so my testing is limited

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.
+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.

If you partition a disk on another system (e.g. laptop),

This is probably due to an error in Au1000 chip.
