[U-Boot-Users] Information about Uboot porting

[eagle keeper]

Hi all,
I'd like to ask for a guide-line.
I have to port u-boot to a ppc board based on mpc860p, but this board has
not bcsr.
I have seen in the code that Uboot enables ethernet rs232 and sdram using
bcsr.
How can I enable RS232, ethernet and sdram without bcsr?
Is there a somehow standard way to procede?

Thanks in advance
Emanuele

PS: Of course I am not asking for the implementation, but only for a
procedure.
