Re: [U-Boot] [PATCH V2 3/6] mv_egiga: bugfix: DMA issue fixed using volatile

You can use volatile qualifier for the variables in DMA specific code instead of modifying structures, Try to use memory barrier or something like that- Some ref : http://gcc.gnu.org/ml/gcc/2003-04/msg01180.html may be someone c-expert on the list can suggest better

Seems we've followed the same line of reasoning. :)

I'll look into forcing a sequence point without resorting to asm.

Amicalement,
