6678从emif flash启动的地址可以是0x74000000么？

常用的启动地址可是0x70000000，而我们的硬件工程师将flash接到6678的0x74000000起始的CE1空间。目前启动不起来。请问flash的空间可以是0x74000000么？

    ROM bootloader是不会把PC指向0x74000000的
    During this process, the RBL just sets the program counter to the base address of the EMIF chip select that is specified through the boot strap pins

    如果一定要从0x74000000读取代码的话，可以先从其它的boot mode如SPI/I2C启动一个二次bootloader代码，这个二次bootloader代码再去从0x74000000搬移代码。
