Hello everyone,
This is based on Roman Stratiienko's work to support boot image header version 3 and 4.
This supports the new boot image headers v3, v4 and bootconfig feature.
https://source.android.com/docs/core/architecture/bootloader/boot-image-head... https://source.android.com/docs/core/architecture/bootloader/implementing-bo...
Tested on Amlogic Khadas vim3l, a reference board for Android Open Source Project https://www.khadas.com/vim3l
And on AM625 Texas Instruments board with 5.10 linux kernel
Main changes :
- New partition : vendor boot, with a specific vendor ramdisk
- DTB is stored in the vendor boot partition
- The generic ramdisk is placed after the vendor ramdisk
- Bootconfig feature support
Here is a link to see the related android boot flow changes on KHADAS vim3l as an example: https://gitlab.baylibre.com/baylibre/amlogic/atv/u-boot/-/commits/souajih/Bo...
