Sam,
sync and msync end up being the exact same thing on e500. Its better to leave the code in drivers and such to use sync since then it will build on non-e500 cores. But all binutils should assemble sync and msync as the same instruction for e500.

Hi,
I found that there was an unclear assembly usage on 'sync' for 85xx in current tree. On P202 of E500CORERM.pdf, it says that 'sync' has replaced by 'msync' in BOOK-E and E500. But there are still some 'sync' for 85xx at cpu/mpc85xx folder and other files like drivers/ tsec.c.
I changed all 'sync' as 'msync' on my customized 8548 boards. Seems no obvious difference. Both OK.
So I wonder whether we should fix it. Thoughts?
Thanks,
Sam
