From: Roland Hieber <rohieb@xxxxxxxxxxx> Pin down the minimal config needed for a Kindle 4/5 device to boot into the vendor Linux. As the board documentation says, there is an upper limit of ~240 KB for the bootloader partition on those devices. Using XZ image compression instead of the default LZO reduced the file size from 214 KB to 172 KB, so enabling that too.
