Hi Marcio,
This is not u-boot related, I think you should post this issue to
Linux kernel mailing list.

I check the NAND flash spec and find you may use wrong
parameters for generating UBIFS image.

Page size x16: 1056 words (1024 + 32 words)

and no sub-page.
So, I think mini I/O unit should be 1024 x 4 = 4096 Bytes

UBI error: ubi_io_read:
error -74 (ECC error) while reading 64 bytes from PEB 2:

This is ECC error, I think you should also update
the driver for atmel_nand.c (mainly ECC layout)
