[U-Boot] instruction "xchgb" for x86_64

[James Wang]

Hi Bin
 
>> This is James and am working on u-boot to bring back MinGW tool chain for cross compiling host tools for Windows on Linux. After complete the code, I plan to generate a patch for community review.

>Do you mean cross compiling U-Boot's mkimage tool for Windows on Linux using gcc-mingw-w64? Do you want to support building U-Boot on Windows as well?

Yes, I am compiling with MinGW-w64, more specifically x86_64-w64-mingw32-gcc on Linux. I don't have setup to build host tools on Windows for now. Maybe I could have a try.
