My MPC8260 based customs board gives the u-boot prompt with IMMR value 
0x0F000000. Now I changed the IMMR to 0xF0000000, but the I can not get 
the Boot prompt, why?   I change the IMMR in u-boot,  as I found in the 
mailing list that for linux to come up we should change the IMMR in u-boot 
to 0xF0000000. Is this true? 

My questions are

1. Is it possible to bring up Linux by u-boot having IMMR 0x0F000000? ( I 
found in the documentation, that in Linux tree I need to set 
IMAP_ADDR=CFG_IMMR , but doing so, does not bring up Linux.  where is the 
wrong? ) . I am bit confused that, in one document says that setting the 
same IMMR value both in U-boot and Linux should bring up Linux and the 
other document says that for Linux to come up IMMR value at u-boot should 
be set as 0xF0000000.  What is the truth?
2. What to change to get boot prompt for IMMR 0xF0000000

The board we are using does not have BCSR.
