4 daysMerge patch series "bootstd: Add Android support"Tom Rini1-0/+6
Mattijs Korpershoek <mkorpershoek@baylibre.com> says: Android boot flow is a bit different than a regular Linux distro. Android relies on multiple partitions in order to boot. A typical boot flow would be: 1. Parse the Bootloader Control Block (BCB, misc partition) 2. If BCB requested bootonce-bootloader, start fastboot and wait. 3. If BCB requested recovery or normal android, run the following: a. Get slot (A/B) from BCB b. Run AVB (Android Verified Boot) on boot partitions c. Load boot and vendor_boot partitions d. Load device-tree, ramdisk and boot The AOSP documentation has more details at [1], [2], [3] This has been implemented via complex boot scripts such as [4]. However, these boot script are neither very maintainable nor generic. Moreover, DISTRO_DEFAULTS is being deprecated [5]. Add a generic Android bootflow implementation for bootstd. For this initial version, only boot image v4 is supported. This has been tested on sandbox using: $ ./test/py/test.py --bd sandbox --build -k test_ut This has also been tested on the AM62X SK EVM using TI's Android SDK[6] To test on TI board, the following (WIP) patch is needed as well: https://gitlab.baylibre.com/baylibre/ti/ti-u-boot/-/commit/84cceb912bccd7cdd7f9dd69bca0e5d987a1fd04 [1] https://source.android.com/docs/core/architecture/bootloader [2] https://source.android.com/docs/core/architecture/partitions [3] https://source.android.com/docs/core/architecture/partitions/generic-boot [4] https://source.denx.de/u-boot/u-boot/-/blob/master/include/configs/meson64_android.h [5] https://lore.kernel.org/r/all/20230914165615.1058529-17-sjg@chromium.org/ [6] https://software-dl.ti.com/processor-sdk-android/esd/AM62X/09_02_00/docs/android/Overview.html

Caleb Connolly <caleb.connolly@linaro.org> says: MMU issues are some of the most frustrating to debug. To make this slightly less unbearable, introduce a software pagetable walker for ARMv8.

This can also be useful to dump the pagetable used by a previous bootloader stage (by reading out the ttbr register). Here is an example of the output when walking U-Boot's own memory map on a Qualcomm RB3 board: Walking pagetable at 000000017df90000, va_bits: 36.
