1.Use "qixis_reset sd" to boot from SD 2.Use "qixis_reset sd_qspi" to boot from SD with QSPI support 3.Use "qixis_reset qspi" to boot from QSPI flash
On some SoCs such as LS1021A and LS1043A, IFC and QSPI could be pin-multiplexed. So the switches are different between SD boot with IFC support and SD boot with QSPI support. The default booting from SD is with IFC support.
