when there are some reasons which board failed to boot, eg rootfs crashes.
/init will fail to panic().
panic()
{
local console rest IFS
if command -v chvt >/dev/null 2>&1; then
chvt 1
fi
echo "$@"
# Disallow console access
if [ -n "${panic?}" ]; then
echo "Rebooting automatically due to panic= boot argument"
sleep "${panic}"
reboot
exit # in case reboot fails, force kernel panic
fi
...
}
when panic is set, there is no chance to fail into a shell, to debug what happens.
and device just keep reboot.
remove panic from bootargs to make it possible for users to find out why their boards fail to boot.

atomic_pool_size can be controlled by kernel cmdline,
coherent_pool=nn[KMG] [ARM,KNL]
then use this parameter to replace the patch.

Setting load_addr to "0x44000000" (1088 MiB) is too high for boards with only 1GB of RAM, and causes boot failure. I tried some lower values, until I found "0x34000000" (832 MiB) to work. I made quite big steps, so we probably could find something slightly higher to work too, but I see no reason why we would need to do it.

- merging C2 and Meson family on the source level, C2 is still making own kernels, but sources, patches and configs are the same
- merged boot scripts for meson family. support for non existing legacy kernel was dropped from boot scripts, added UUID support, armbianEnv.txt
- Meson default remain on 4.14.y, NEXT moved to 4.17.y and DEV remains on master
- remove deprecated patches, remove wrong permissions in patches
- tested on C2, K2 and Le Potate. USB troubles are still present and common, while K2 and Lepotato might have boot/reboot troubles on 4.16+
- boards configuration cleanup
- moving K2 to the supported list. It's the same level of support as Le Potato
