There's a lot more work to be done around platforms that enabled
sha1/sha256 this way and confirming that it was actually unusable code.
For example, (as it was where I stopped paging at in less just now)
ls1043aqds_nor_ddr3 drops sha256 and md5 algorithm support, I suspect
because of this hunk, but could be some other part of the series.  Using
buildman's --show-sizes --bloat can be really handy to see when a patch
drops out a bunch of code, or adds it in.
