From 95f4bbd581cfde45d4bd1fa5e56c2d880dae7ced Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 8 Mar 2019 16:06:55 +0100 Subject: lib: fdt: Allow LZO and GZIP DT compression in U-Boot Add required Kconfig symbols, Makefile bits and macro fixes in a few places to support LZO and DT compression in U-Boot. This can save a lot of space with multi-DTB fitImages.
