The header of the StarFive U-Boot SPL file u-boot-spl.normal.out has a
field indicating the payload size. When copying U-Boot SPL from a
partition the copied file might be too long.
Currently in this situation a misleading error message 'Incorrect CRC32' is
written.
We must use the payload size and not the file size when calculating the
CRC32.
Write a warning if the file is too long indicating the correct size. This
enables the user to truncate the file accordingly.
