Android 10 brings a lot of new requirements for bootloaders: [1]. This patch series attempts to implement such a boot process on BeagleBoard X15 platform. Some common code is added too, which can be reused later for other platforms.
This patch series denends on next (still not merged) patches: 1. libavb: Update libavb to current AOSP master [2] 2. libavb: Fix build warnings after updating the lib [3] 3. cmd: avb: Support A/B slots [4] 4. cmd: avb: Fix requested partitions list [5]
Changes in v2: - add the unit test for new functionality ('bootimg' command, dtb/dtbo fields in Android Boot Image) - add "bootimg set_addr" sub-command - provide mem mappings so that 'bootimg' command works in sandbox (needed for tests to work correctly) - rebase on top of most recent master - re-sync am57x defconfigs with "make savedefconfig"
