Subject: Add bbenv-y support
Date: Tue, 25 Feb 2014 15:18:00 +0100	[thread overview]
Message-ID: <1393337884-17282-1-git-send-email-s.hauer@pengutronix.de> (raw)

Currently we can build images for multiple boards at once, but
all share the same default environment. As a last step to real
multi image support this patchset changes this.

bbenv-y is a Makefile target which can be used to generate default
environment snippets. Boards can use it as:

bbenv-$(CONFIG_SOMETHING) += my-environment

The directory containing the files to compile into the binary
should be named my-environment.

This can be accessed in C code later as:

extern unsigned char __bbenv_my_environment_start[];
extern unsigned char __bbenv_my_environment_end[];

The defaultenv snippet can then be registered using defaultenv_append().

With this each board will find the environment it expects during runtime.
