Hi,
(CCing u-boot mailing list and Mike Frysinger)
stdlib.h is indeed missing.
EXIT_FAILURE and EXIT_SUCCESS are defined within stdlib.h, so that
explains it.
How old are you u-boot sources ? compiler.h has been introduced by:
commit 37566090766d61beef70c62986b90749920255d8
Author: Mike Frysinger <vapier at gentoo.org>
Date: Thu Jul 2 19:23:25 2009 -0400
If your U-Boot is older than that, could you please test again with the
latest possible version ? Btw, cpu_to_be32 is defined within compiler.h
Thanks for testing and reporting.
Regards,
David.
