But address_space_rw() is just the "memcpy bytes to the target's memory" operation -- if you have a pile of bytes then there are no endianness concerns. If you don't have a pile of bytes then you need to know the structure of the data you're DMAing around, and you should probably have a loop doing things with the specify-the-width functions. thanks -- PMM
