Your patch fixes the Error message but still I do not  get any o/p on
serial with the resulting u-boot.rom

I only way I have dumped SPI flash has been through flashrom only.
How else can I do it on Linux?

As of now I am trying to burn u-boot.rom with SPI programmer/software
on Windows to check the sanity of my flashrom setup.
