To support the Platform better,I added LCD panel(NL6448BC20-08) function.But bewear of
the fact that once you build this support and program it to FLASH,you should make sure
you put workable kernel and ramdisk at the right place in FLASH or through NFS.
Otherwise, you must erase this fireware manually via BDI2000 or ICE tools.So this
function is used for deployment and demo only.Pls look before you leap.

A word on the U-Boot enviroment variable setting and usage :
In the beginning, you could just need very simple defult environment variable setting,
like[include/configs/RPXlite.h] :
#define CONFIG_BOOTCOMMAND \
"bootp; " \
"setenv bootargs root=/dev/nfs rw nfsroot=$(serverip):$(rootpath) " \
"ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname)::off; " \
"bootm"
This is enough for kernel NFS test. But as debug process goes on, you would expect
to save some time on environment variable setting and u-boot/kernel updating.
So the default environment variable setting would become more complicated. Just like
the one I did in include/configs/RPXlite_DW.h.
Two u-boot commands, ku and uu, should be careful to use. They were designed to update
kernel and u-boot image file respectively. You must tftp your image to default address
'100000' and then use them correctly. Yeah, you can create your own command to do this
job. :-) The example u-boot image updating process could be :

u-boot updating finished
u-boot>
Also for environment updating, 'run eu' could let you erase OLD default environment variable
and then use the working u-boot environment setting.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Finally, if you want to keep the serial port to possible debug on spot for deployment, you
just need to enable 'DEPLOYMENT' in RPXlite_DW.h as 'DEBUG' does. Only the special string
defined by CONFIG_AUTOBOOT_STOP_STR like 'st' can stop the autoboot.
I'd like to extend my heartfelt gratitute to kind people for helping me work it out.
I would particually thank Wolfgang Denk for his nice help.

DbAu1000 is a development board from AMD containing
an Alchemy AU1000 with mips32 core.
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
----------------------
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
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.
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 only supported for slot 0, only 3.3V.
Pcmcia IDE tested with Sandisk Compact Flash and
PCMCIA IDE tested with Sandisk Compact Flash and

If you partition a disk on another system (e.g. laptop),
all bytes will be swapped on 16bit level when using
PCMCIA!!!!
PCMCIA and running cpu in big endian mode!!!!
This is probably due to an error in Au1000 chip.
