Issue about downloading SDK

Hi, The README of this project suggests https://downloads.openhwgroup.org/ link to download the SDKs, but it is redirected to home https://openhwfoundation.org/ instead of viewing the download page. It seems the AWS redirection links for those files which were on the download page are still available, but they can't be found at ease either. Are the SDKs previously existed out of support, or should new links for them be updated to README?
