[U-Boot-Users] Information about Uboot porting
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.

You are lucky, then.

Umm.... only very few boards use a BCSR.

Yes, there is. Check any 8xx board excluding the Motorola/Freescale boards... The standard is NOT having a BCSR.
