There are typically two types to set the mtd partitions:
<1> set with the `size`, such as gpmi-nand:100m(boot),100m(kernel),1g(rootfs)
<2> set with the `offset`, such as gpmi-nand:100m@0(boot),100m@100m(kernel),1g@200m(rootfs) gpmi-nand:1g@200m(rootfs),100m@0(boot),100m@100m(kernel)
If we mix these two types, such as: gpmi-nand:100m@0(boot),100m(kernel),1g@200m(rootfs) gpmi-nand:1g@200m(rootfs),100m@0(boot),100m(kernel)
It's hard to understand the cmdline. And also it is hard to sort the partitions in this mixed type. So we explicitly forbid the mixed type.
