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.
