-# GKI boot image retrofitting tools for upgrading devices
-
-Starting from Android T the GKI boot images consist of the generic `boot.img`
-and `init_boot.img`. The `boot.img` contains the generic kernel, and
-`init_boot.img` contains the generic ramdisk.
-For upgrading devices whose `vendor_boot` partition is non-existent, this tool
-(or spec) can be used to retrofit a set of Android T GKI `boot`, `init_boot` and
-OEM `vendor_boot` partition images back into a single boot image containing the
-GKI kernel plus generic and vendor ramdisks.
-
-## Retrofitting the boot images
-
-1. Download the certified GKI `boot.img`.
-2. Go to the build artifacts page of `aosp_arm64` on `aosp-master` branch on
-   https://ci.android.com/ and download `gki_retrofitting_tools.zip`.
-3. Unzip and make sure the tool is in `${PATH}`.
-
-   ```bash
-   unzip gki_retrofitting_tools.zip
-   export PATH="$(pwd)/gki_retrofitting_tools:${PATH}"
-   # See tool usage:
-   retrofit_gki --help
-   ```
-
-4. Create the retrofitted image. The `--version` argument lets you choose the
-   boot image header version of the retrofitted boot image. Only version 2 is
-   supported at the moment.
-
-   ```bash
-   retrofit_gki --boot boot.img --init_boot init_boot.img \
-     --vendor_boot vendor_boot.img --version 2 -o boot.retrofitted.img
-   ```
-
-## Spec of the retrofitted images
-
-* The SOURCE `boot.img` must be officially certified Android T (or later) GKI.
-* The DEST retrofitted boot image must not set the security patch level in its
-  header. This is because the SOURCE images might have different SPL value, thus
-  making the boot header SPL of the retrofitted image ill-defined. The SPL value
-  must be defined by the chained vbmeta image of the `boot` partition.
-* The `boot signature` of the DEST image is the `boot signature` of the DEST
-  `boot.img`.
-* The DEST retrofitted boot image must pass the `vts_gki_compliance_test`
-  testcase.
-
-### Retrofit to boot image V2
-
-* The `kernel` of the DEST image must be from the SOURCE `boot.img`.
-* The `ramdisk` of the DEST image must be from the SOURCE `vendor_boot.img` and
-  `init_boot.img`. The DEST `ramdisk` is the ramdisk concatenation of the vendor
-  ramdisk and generic ramdisk.
-* The `recovery dtbo / acpio` must be empty.
-* The `dtb` of the DEST image must be from the SOURCE `vendor_boot.img`.
-* The `boot_signature` section must be appended to the end of the boot image,
-  and its size is zero-padded to 16KiB.
-
-```
-  +---------------------+
-  | boot header         | 1 page
-  +---------------------+
-  | kernel              | n pages
-  +---------------------+
-  | * vendor ramdisk    |
-  |  +generic ramdisk   | m pages
-  +---------------------+
-  | second stage        | o pages
-  +---------------------+
-  | recovery dtbo/acpio | 0 byte
-  +---------------------+
-  | dtb                 | q pages
-  +---------------------+
-  | * boot signature    | 16384 (16K) bytes
-  +---------------------+
