Re: [U-Boot] [PATCH] [v2] powerpc: fix implementation of out_8 to match the other out_XX functions

Dear Timur Tabi,

In message 1301952064-1418-1-git-send-email-timur@freescale.com you wrote:

For some reason, the implementation of out_8() does not match the other output accessors, nor does it match equivalent Linux accessor. This can cause a problem in a situation like this:

__raw_readb(p1); out_8(p2, x);

In this case, there is no barrier between the read and the write. If the out_8() is changed to out_be16(), then there is a barrier.
