[U-Boot-Users] SDRAM initialization process - U-BOOT1.1.1

Hello,

we are in the process of initializing the SDRAM refresh procedure with 
MPC8260.
As we get started, we have seen that u-boot.1.1.1 code includes two 
functions
which includes:
board/mpc8260ads/mpc8260ads.c   initdram()
cpu/cpu.c                                    upmconfig()

we have seen that initdram() is called from  init_func_ram() in 
board/lib_ppc/board.c
Also, init_func_ram() is a function pointer in the array init_sequence[].

we have not seen that the function upmconfig() is ever called for 
MPC8260ads, and
we would like to know whether we should call it.

Currently, we have the u-boot1.1.1 reaching the relocate_code to the point 
where
the kernel image is copied from Flash to SDRAM, but the image in the SDRAM 
is corrupted.

The question is: is there a bug in the mpc8260ads that does not call the 
upmconfig()
or we should not call it at all?

Looking forward for your input.

Regards,
Ronen
