-## Recovery Disk Image
-
-The Mk4 bootloader is smart enough to read an SD card. However, you
-will only be able to trigger the SD card loading code, if the system
-is powered-down during the upgrade process. At that point, the
-intended (new) firmware image has been lost because it it held in
-PSRAM (volatile memory) during the flash writing process.
-
-The bootloader will only install an image of exactly the same version
-as was being installed when interrupted. This is done by verifying
-the checksum vs. a value set in SE1 by the pin-holder. This prevents
-side-loading or up/downgrade attacks.
-
-This directory holds data and code to build a special SD-card disk
-image with all possible releases. The goal is a single disk image that
-can be used restore a Coldcard of any (intended) version.
