Hi Shawn/Leo, Removing the "big-endian" property has caused problems in our UEFI firmware. In UEFI, we use the device tree to detect and use the qspi controller and flashes attached to it. We don't maintain a list of platforms like linux driver.
Can you please revert the endianness change from linux mainline ?
