Hi All, 

I have RAM version of U-Boot which is running on a board similar to MPC8260. My memory map isas follows: 

Staring address                Device                Size                      Memory controller and CS 

      0000 0000 
      0800 0000 
      FFF0 0000 
      0F00 0000 
      3000 0000 
      3800 0000 
      4200 0000 
      5000 0000  FLASH (Boot) 
      FLASH (Code)

      128 MB (16Mx72) 
      1 MB 
      2 MB  BR0/OR0: CS0 
      BR1/OR1: CS1 
      BR2/OR2: CS2 

      BR3/OR3: CS3 
      BR4/OR4: CS4 
      BR5/OR5: CS5 
      BR6/OR6: CS6 



This configuration will not work for linux.  Linux needs to run in SDRAM starting at zero (notice
'Load Address' and 'Entry Point' just before 'uncompressing image'.)
