From 6768f39a4b5a5d6d1c2318f632f801fe1c8084cd Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sat, 3 Oct 2009 16:24:58 +0000 Subject: Remove: - CONFIG_CBFS - anything that's conditional on CONFIG_CBFS == 0 - files that were only included for CONFIG_CBFS == 0 In particular: - elfboot - stream boot code - mini-filo and filesystems (depends on stream boot code) After this commit, there is no way to build an image that is not using CBFS anymore.
