Alexandru Gagniuc1d857002015-09-09 22:38:06 -070033# We just mash all microcode binaries together into one binary to rule them all.
34# This approach assumes that the microcode binaries are properly padded, and
35# their headers specify the correct size. This works fairly well on isolatied
36# updates, such as Intel and some AMD microcode, but won't work very well if the
37# updates are wrapped in a container, like AMD's microcode update container. If
38# there is only one microcode binary (i.e. one container), then we don't have
39# this issue, and this rule will continue to work.
