I didn't have CONFIG_MTD_OF_PARTS=y.

Know, I have this output:

 Found: Intel I28F016S3
fe000000.flash: Found 4 x8 devices at 0x0 in 32-bit bank
fe000000.flash: Found an alias at 0x800000 for the chip at 0x0
fe000000.flash: Found an alias at 0x1000000 for the chip at 0x0
fe000000.flash: Found an alias at 0x1800000 for the chip at 0x0
erase region 0: offset=0x0,size=0x40000,blocks=32
RedBoot partition parsing not available
Creating 3 MTD partitions on "fe000000.flash":
0x0000ff800000-0x0000ffc00000 : "kernel"
mtd: partition "kernel" is out of reach -- disabled
mtd: Giving out device 0 to kernel
0x0000ffc00000-0x0000fff00000 : "user"
mtd: partition "sofrel" is out of reach -- disabled
mtd: Giving out device 1 to user
0x0000fff00000-0x000100000000 : "u-boot"
mtd: partition "u-boot" is out of reach -- disabled
mtd: Giving out device 2 to u-boot

I think that the problem is in the reg part, but I can't understand why.
Isn't it the RAM mpping of my MTD that is the first address ?

Thanks agains,
