[U-Boot-Users] porting u-boot

[Peter Asemann]

I'm still into porting u-boot to a full-custom board.
The u-boot README says that the u-boot will scan for my SDRAM and find 
out how much I have.
I suppose that will only work if I write a custom SDRAM-setup-procedure 
..../u-boot/board/CUSTOMBOARD/customboard.c ? Is that right?

If so, is there any documentation about what needs to be done there?
I believe that the sdram_table array used in all those board_name.c 
files contains hexadecimal encoded instructions programming the UPM.. am 
I right?

Well... any hints (like, for example, "RTFM manual/ressource name") are 
welcome.

You cannot avoid this, right (you need it even if you set  up  for  a
fixed memory size only).

Sure. See the processor's User's manual and related documentation.

Here we go: RTFM the processor documentation and related material ;-)

[U-Boot-Users] Porting U-boot

[calvin]

I am trying to port U-boot to a board which uses Galileo(GT64120) system 
controller to access SDRAM. does any of the boards supported by U-boot 
have a similar interface ?


Thanks and Regards,
Pooja

  HELLO EVERYONE 
    i am porting u-boot to my hardware my arm is philips lpc2210 . in the readme  ,i find that  "	1.  Add a new configuration option for your board to the toplevel
    "Makefile" and to the "MAKEALL" script, using the existing"
  i don't understand this sentence.   my arm is arm7-tdmi.  i use the "S3C44B0 Systems"  in  in the Makefile, i add some lines as  following.but i don't understand what means? is it right?

I'm sorry. But this will not work. Please stop posting  two  messages
with questions for every single line of code you write.

Please try to get some understanding first.  If  you  don't  succeed,
then tryu to get some training for such work, or hire a guru.


We will NOT explain you every single line of code here.
