As a side project I've created a fairly simple performance improvement for the linaro-media-create tool. Basically the copying of the root_fs happens earlier in the process such that hwpack and a number of other steps are done in parallel and then at the end there's one last rsync to make sure adjusted files, further installed files are correctly copied.
There might be an interesting speedup + bugfix in aligning the rootfs partition on a power of two, e.g. 1 MiB boundary, as the SD/MMC is flash internally, and undergoes erase/write cycles for fs meta-data. I think only OMAP has constraints on the number of heads/sectors, but we could take a factor of that: 63*255 can't really be factored well, but we could use LBA addressing and start in the middle of a cylinder.
