With LTO enabled the U-Boot initial environment is no longer stored in an easy accessible section in env/common.o. I.e. the section name changes from build to build, its content maybe compressed and it is annotated with additional data. Drop trying to read the initial env with elf tools from the compiler specific object file in favour of adding and using a host tool with the only functionality of printing the initial env to stdout.

# We are using a recursive build, so we need to do a little thinking
|
|
# to get the ordering right.
|
|
#
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
# their own directory. If in some directory we have a dependency on
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
# after that we are sure that everything which is in that other dir
|
|
# is now up to date.
|
|
#
|
|
# The only cases where we need to modify files which have global
|
|
# effects are thus separated out and done before the recursive
|
|
# descending is started. They are now explicitly listed as the
|
|
# prepare rule.

|
|
#
