test_abootimg is extended to include the testing of boot images version 4. For this, boot.img and vendor_boot.img have been generated using mkbootimg tool with setting the header version to 4. This tests: - Getting the header version using abootimg - Extracting the load address of the dtb - Extracting the dtb start address in RAM Running test: $ ./test/py/test.py --bd sandbox --build -k test_abootimg Signed-off-by: Safae Ouajih <souajih@baylibre.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Mattijs Korpershoek <mkorpershoek@baylibre.com>

These tests rely on disk image (boot.img), which is automatically created by
|
|
the test from the stored hex dump. This is done to avoid the dependency on the
|
|
most recent mkbootimg tool from AOSP/master. Here is the list of commands which
|
|
was used to generate the boot.img and obtain compressed hex dump from it:
|
|
|
|
$ echo '/dts-v1/; / { model = "x1"; compatible = "y1,z1"; };' > test1.dts
|
|
$ echo '/dts-v1/; / { model = "x2"; compatible = "y2,z2"; };' > test2.dts
|
|
$ dtc test1.dts > dt1.dtb
|
|
$ dtc test2.dts > dt2.dtb
|
|
$ cat dt1.dtb dt2.dtb > dtb.img
|
|
$ echo 'kernel payload' > kernel
|
|
$ echo 'ramdisk payload' > ramdisk.img
|
|
$ mkbootimg --kernel ./kernel --ramdisk ./ramdisk.img \
|
|
--cmdline "cmdline test" --dtb ./dtb.img \
|
|
--os_version R --os_patch_level 2019-06-05 \
|
|
--header_version 2 --output boot.img
|
|
$ gzip -9 boot.img
|
|
$ xxd -p boot.img.gz > boot.img.gz.hex
|
|
|
|
Now one can obtain original boot.img from this hex dump like this:
|
|
|
|
$ xxd -r -p boot.img.gz.hex boot.img.gz
|
|
$ gunzip -9 boot.img.gz
|
|
|
|
For boot image header version 4, these tests rely on two images that are generated
|
|
using the same steps above :
|
|
|
|
1- boot.img :
|
|
$ mkbootimg --kernel ./kernel --ramdisk ./ramdisk.img \
|
|
--cmdline "cmdline test" --dtb ./dtb.img \
|
|
--os_version R --os_patch_level 2019-06-05 \
|
|
--header_version 4 --output ./boot.img
|
|
|
|
2- vendor_boot.img
|
|
$ mkbootimg --kernel ./kernel --ramdisk ./ramdisk.img \
|
|
--cmdline "cmdline test" --dtb ./dtb.img \
|
|
--os_version R --os_patch_level 2019-06-05 \
|
|
--pagesize 4096 --vendor_ramdisk ./ramdisk.img \
|
|
--header_version 4 --vendor_boot ./vboot.img \
