hello,

I try to load from JFFS2 filesystem , the kernel,rootfs and DTB. and I 
have bad data CRC error on my file.
Have you any idea of the reason ?
I try to copy several kernel image in the filesystem i've got the same 
error, also with rootfs.
I've no problem with "raw" file and using  nand read in other MTD with 
the same kernel,rootfs, dtb.

environnement :
     - u-boot 2013 from SDK freescale 1.4
     - linux 3.8.13 from SDK freescale 1.4
    - custom board based on P2020

  STEP 1
     - In Linux mount JFFS2 file system and copy kernel, rootfs and DTB.
STEP 2
     - In U-boot
fsload 1000000 uImage
### JFFS2 loading 'uImage' to 0x1000000
### JFFS2 load complete: 3287019 bytes loaded to 0x1000000
