 Limitations & comments

-I assume that you set board to BIG endian!

+Support was originally big endian only.
+I have not tested, but several u-boot users report working

 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!

 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.

+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.

 This is probably due to an error in Au1000 chip.
