From 44431cabbb66e81a2d77642b6f7d39c6230ea4ba Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 21 Jan 2010 19:30:36 -0500 Subject: [PATCH] gzip/zlib: make features optional If you really want to slim down U-Boot and you would rather use a higher compression scheme (like LZMA), it'd be nice to disable gzip/zlib since these code bases take up a significant amount of space.
