Description
Working on https://github.com/linuxboot/heads/pull/1570/ the following next steps are needed
- [ ] dgpu blobs (t530 dgpu/w530 dgpu+igpu board flavors) scripts are complicated and fail to work under debian-12
- [ ] haswell blobs are downloaded at each builds per CI since not part of CircleCI prep step (650mb download to extract MRC blob!!!!)
- [ ] review scripts so that first step is to check extracted blobs existence + hash prior of redownloading (done for xx20_me/xx30_me but none other scripts)

Research direction
Read the CircleCI prep step and the blob download scripts under the blobs directory, then compare the existing xx20_me and xx30_me hash checks with the dgpu and haswell scripts. Verify the scripts work on Debian 12, avoid repeated haswell downloads, and only download when extracted blobs or their hashes are missing or invalid.
