I got a 2.9G image that I flash via fastboot to the eMMC and that takes quite a while on my i.MX6Q. Instead of fixing my image generation to make proper use of the sparse format's don't care chunk types to save oneself from writing all these holes at the end of the partitions, I went the easy route by tweaking the block layer a bit: barebox v2020.02.0: 445s With first patch: 376s With second patch: 300s Of these 300s, 180s are spent writing zeroes...
