From: Quanyang Wang <quanyang.w...@windriver.com>
In the commit 996ca36db0e5 ("arm64: zynqmp: adjust qspi flash partition"),
I adjust the partition "qspi-rootfs" to cover the address 0x1e00000.
But this address is used to store the parameters for u-boot v2019.2 by
default. Erase this partition will corrupt parameters data. So split
"qspi-rootfs" partition into "qspi-rootfs", "qspi-uboot-parameters"
and "qspi-test" to avoid this.
