I think so.The case of LITE_DW is XPC823EZT66B2 with
8MHz,mine is XPC823EZT75B2 with 8MHz.Our SDRAM part
design base on LITE_DW. Also use same chips and hope
we could go smoothly on development.In addition,I
tested burst write with unreasonable configuration on
LITE_DW and it could get through(I mean U-Boot booted
normally on LITE_DW but not test further for possible
results).So I focus my mind on six RAM WORD of UPMA
BURST READ.

Best regards,
