Hello Thomas, I haven't got to look into that register:
uboot is updated to v2011.12-2014_T2.0 and everything
is working! So thanks once again.
The only problem I now have is the lack of 256Mb of

[    0.000000] MEMBLOCK
[    0.000000]  memory size = 0x1f0000000 reserved size =
[    0.000000]  memory.cnt  =
[    0.000000]  memory[0x0]     [0x00000000000000-0x000000efffffff],
bytes flags:
[    0.000000]  memory[0x1]     [0x00000100000000-0x000001ffffffff],
 bytes flags: 0x0 

There is a 8Gb in a single dimm.
Do you have any idea why 0xf0000000-0xffffffff range is missing?
I suspect this is something with uboot too.
