Each +individual file represented a single platform's microcode. However, +recently Intel has changed that policy and is no longer distributing +microcode in that fashion. Further, we also relied on bootadm to go +through and turn this microcode into individual files as part of setting +up the boot environment. + +Intead of using this method, we will update the microcode and manage +them in here as individual files. When updating files, please indicate +the release that the microcode was obtained from here. + +AMD: Updated in March 2012 as part of illumos#2546.
