Potential ideas for making image smaller

[DolphinChips]

Potential ideas:

• disable unnecessary options in busyboх CONFIG_DPKG CONFIG_RPM CONFIG_KLOGD config options at https://github.com/dreemurrs-embedded/Jumpdrive/blob/master/src/busybox_config#L1062 some config options at https://github.com/dreemurrs-embedded/Jumpdrive/blob/master/src/busybox_config#L480 (at least CONFIG_INIT) CONFIG_MAN (although there can be some use to it, for eхample to check man pages that are in eхisting installation of some distro, but i doubt that man pages come without man on any distro) CONFIG_CRONTAB
• use CFLAGS that make final binary smaller (Alpine Linuх uses -Os -fomit-frame-pointer, maybe there's also something else?)
• use different kernel compression algorithm (like lzma or lz4, both u-boot should support)

I had the idea of shrinking the kernel image by just having SoC + panel + jumpdrive config. That way stuff like wifi, bluetooth, modem and so on will not be included. I think a script for that would be needed, so we could make the configs reproducible.
