Did you try if the memory is accessible on your platform ? AR9331 I have here has the SRAM at 0xbd007000 , just like that machine in [1] .
I found there is a memory segment at 0xbd000000...0xbd007fff. it's independent of DDR physical memory, can be read and wrote, but hardware can't boot up if don't execute lowlevel_init.S when define CONFIG_SYS_INIT_SP_ADDR=0xbd007000 to set C stack into SRAM.
