Re: [U-Boot-Users] struct NS16550 {...} __attribute__ ((packed)) at ns16550.h

Dear Arthur,

in message 003501c549d3$7d67aa00$1780a8c0@art you wrote:

There are discussions on this on the GCC mailing list going back a ways; a notable one (that mentions m68k as another platform that generates byte accesses besides ARM) is at http://gcc.gnu.org/ml/gcc/1997-10/msg00063.html while a more recent bug report hinting at this fact is at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=12200

Thanks for digging this out.

So the real fix for this problem should be to use a proper "__attribute__((aligned(?)))" where struct NS16550 is instantiated.

Best regards,
