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. -- Loïc Minier _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
