Just a guess: You are using imx_nand_load_image() with a fixed size of 256k. grep for this function in the current tree and see how the correct image size is calculated.

imx_nand_load_image() is never used in my imx53 board init code.. is this the fault?

Just a guess:

You are using imx_nand_load_image() with a fixed size of 256k. grep for
this function in the current tree and see how the correct image size is
calculated.
