Hi All,

I have RAM version of U-Boot which is running = on a board=20 similar to MPC8260. My memory map isas follows:

Staring address         =    =20    Device               =  Size=20                    =20  Memory controller and CS
0000 0000 =
0800 0000
FFF0 0000
0F00 0000
3000 0000
3800 0000
4200 0000
5000 0000=20 		FLASH (Boot) =
FLASH (Code)
SSRAM
CPU internal registers =
SDRAM
SDRAM
Framer
DSP 8102=20 		1MB (512Kx16) =
4 MB (1Mx16)
2 MB (512Kx36)
128 KB
128 MB (16Mx72)
128 MB (16Mx72)
1 MB
2 MB=20 		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=20 linux.  Linux needs to run in SDRAM starting at zero = (notice
'Load Address' and 'Entry Point' just = before=20 'uncompressing image'.)
