[PATCH] pbl: set IMAGE_COMPRESSION per default to lz4

[PATCH] pbl: set IMAGE_COMPRESSION per default to lz4

[Marco Felsch]

The LZO compression hasn't been updated since 2017 and embedded build
tools like Yocto dropping the support for it [1]. So switch to LZ4 as
default since this seems to be the most comparable compression standard
according Ahmads measurements [2] and the kernel suggestion [3].
