From 4af4b69f71b7a7280b1d2898d8829924f3a7b28c Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Wed, 14 Apr 2021 11:56:33 +1200 Subject: ref-manual: add FIT_KERNEL_COMP_ALG* Add FIT_KERNEL_COMP_ALG and FIT_KERNEL_COMP_ALG_EXTENSION. Examining OE-Core commit 5c72105e2973e613b5c0f0e6310ffdea6e56c6c7 and the associated code, these do not enable arbitrary selection of compression algorithm - only disabling compression - so document them accordingly.
