<br><font size=2 face="sans-serif">The board has two GE port on TSEC using
BCM5461S,two serial port on UART using SP3232.</font>
<br><font size=2 face="sans-serif">How can I porting the u-boot to fit
my board?</font>
<br>
<br><font size=2 face="sans-serif">I have completed the first stage by
this:</font>
<br><font size=2 face="sans-serif">1.Add MYBOARD_config option to the top
level of u-boot.</font>
<br><font size=2 face="sans-serif">2.cp board/cds/mpc8541cds/* board/cds/MYBOARD/</font>
<br><font size=2 face="sans-serif">3.rename mpc8541cds.c to MYBOARD.c and
replace "mpc8641cds" with "MYBOARD" in some files</font>
<br><font size=2 face="sans-serif">4.cp include/configs/mpc8541cds.h MYBOARD.h</font>
<br><font size=2 face="sans-serif">5.make MYBOARD_config,make,</font>
<br><font size=2 face="sans-serif">6.It success build, of course not work
on the target.</font>
<br>
<br><font size=2 face="sans-serif">I know that I must custom the files
below MYBORD dir, but any others? especially the UART ,BootRom and flash
drivers.</font>
<br><font size=2 face="sans-serif">I find some messages about BCM5461S
driver in the mail list,how can I get it?</font>
<br>
<br><font size=2 face="sans-serif">I'm newer of using u-boot.Any help will
be appreciated</font>
