# U-Boot patchesThe patches and base U-Boot environment come from Robert Nelson'sBootloader-Builder project for the BeagleBones and other boards.See https://github.com/RobertCNelson/Bootloader-Builder/tree/master/patchesThe strategy is to follow his patches pretty closely, but to make the followingmodifications:1. Store the U-Boot environment raw on MMC. Upstream stores it in a file and that's not as convenient.2. Enable SquashFS. Nerves uses read-only SquashFS root filesystems rather than writable EXT4 ones.3. Support A/B firmware updatesThe U-Boot environment and A/B changes force replicating and modifying thedefault environment to the uboot.env file.
