Verify that using a Mediatek recovery boot.img file works with
bootimg_analyze. The mtk_mkimage-boot.img file is the twrp boot.img file
posted in pmbootstrap issue 2066.
Replace the previous mtkimage-boot.img file, which were only the first 4
KiB of a mediatek boot.img file, with a full one. I made this full image
with pmbootstrap install for fairphone-fp1, it contains the kernel
packaged in pmaports.git master.
Reason for the replacement is, that the previous image did not contain
the label for the ramdisk. The current code ignored this, but upcoming
refactoring will test this more strictly and the dummy image will not
pass the test anymore.
Some Mediatek devices have a special 512-byte header around the zImage
which must be generated so the device boots.
Support for that exists for a while in postmarketOS but detection was
missing. Add that.
postmarketOS/pmaports!700 adds a new "deviceinfo_bootimg_dtb_second"
option that places the DTB in the "second" area of the Android boot
image.
Attempt to detect this automatically by checking the extracted
second binary for the FDT magic (0xd00dfeed).
