From 5c72105e2973e613b5c0f0e6310ffdea6e56c6c7 Mon Sep 17 00:00:00 2001 From: Sinan Kaya Date: Wed, 18 Nov 2020 20:21:17 +0000 Subject: kernel-uboot: allow compression option to be configurable While some platforms might choose to compress the kernel by default especially when boot medium is slow, others want uncompressed kernel. The choice of decompression speed vs. load speed is very platform dependent. Allow platform to choose the option here.
