I'll point it out here rather than Simon. As part of https://github.com/open-source-firmware FIT is a standard and not "boot loader specific". And one of the points of a FIT image is that you can easily support multi-platform kernels in a single file (without optimizing things further, at a cost in tens of milliseconds on a Pi 3 anyhow) and with user-controlled security. -- Tom _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
