I'd like to move the new spl/. I have one question about the new spl/
I didn't see the new spl/ link to nand_spl/nand_boot.c. so how the new
spl/ using nand_boot()?

can we add a new define 'CONFIG_SPL_START_S_NAME', since qi_lb60 using
start_spl.S for SPL, not start.S.

I think better I make the nand_spl/ working. then move to the new spl/ :)

when I remove the -O2. it give me error:
  jz4740.c:(.text.sdram_init+0x14): undefined reference to `memcpy'
so I keep the -O2 there. please anyone give me some advice on how to fix this.
that will be great.

thanks again
