This patch adds QSPI boot support for LS1021AQDS/TWR board. The QSPI boot image need to be programmed into the QSPI flash first. Then the booting will start from QSPI memory space.

Is it necessary to undef?
[Alison Wang] It is necessary, because this file includes "include/config_cmd_default.h". In include/config_cmd_default.h, CONFIG_CMD_IMLS is defined.
Thanks.
[Alison Wang] I may misunderstand your meaning. For QSPI boot, IFC is disabled because IFC and QSPI are pin multiplexed, so CONFIG_CMD_IMLS should not be defined too.
