    Use a mainline U-Boot and non-signed kernels on Exynos Chromebooks

    In a previous post, I explained how to boot a mainline Linux Kernel to use a standard distribution on a Samsung Chromebook by installing it in the unused KERN-C and ROOT-C partitions of the internal eMMC. The kernel binary was contained in a signed FIT image since the read-only vendor bootloader can only boot signed images. The Many Ways to Boot Linux This is only one of the approaches that can be used to boot a mainline kernel. Another technique is to boot a signed u-boot image instead of a kernel, this process is called chain loading since the bootloader loads another bootloader rather than an operating system kernel. Non-signed kernels can be booted by chain loading a signed u-boot; this makes development easier and is more aligned with the development process on ARM platforms that don’t require verified boot. Another option would be to replace the stock vendor bootloader […]
