Switch the kernel compression algorithm to xz from previous gzip default. In testing, cRIO-903x and cRIO-904x show a 2.5MB (27.2%) kernel image size decrease. This also improves the boot time by - 4.8 seconds (12.8%) on cRIO-903x - 2.9 seconds (10%) on cRIO-9043 Signed-off-by: Gratian Crisan <gratian.crisan@emerson.com>

So does the kernel uncompress itself during boot? And we don't need any changes in bootloader? |

Yes, the kernel uncompresses itself, no changes needed to the bootloader. |
