hi Manoel,

I believe you are using current u-boot from upstream to make it work.
In that you need to manually apply this patch on the top of denx.de uboot http://patchwork.ozlabs.org/patch/1091524/
This patch was preempted since maintainers wants to port Linux qspi driver to u-boot.

After applying this you need to add another patch which I will mail you one-on-one. I did not post it upstream stream since it was dependent on my first patch and
Maintainers have suggested that since this fsl-qspi.c will be removed so, they will not accept any further patch for current uboot driver.

For MX25U25645GMI00, please send me data sheet and u-boot log I can help with spi-nor-id.c patch.
