Subject: x86: Don't repeat microcode in U-Boot if not needed
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=4f1f507298e152a97d2aef31c1cd7d9fdec1dafc;p=u-boot.git

x86: Don't repeat microcode in U-Boot if not needed

At present if SPL sets up the microcode then it is still included in
U-Boot as well. This is wasteful as microcode is large. Adjust the logic
in the image to prevent this.
