Hopefully people are OK with this, if not I can revert. Let me know. Best regards, Thomas

elf2flt does not support ARM big-endian, so supporting Cortex M3/M4/M7 with armeb is not possibly. Therefore this commit makes: - MMU mandatory on armeb - Prevents from seeing Cortex M3/M4/M7 on armeb Fixes: http://autobuild.buildroot.net/results/9bca0cbfb6a66c455e74ad194526bca942665978/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> --- arch/Config.in | 2 +- arch/Config.in.arm | 3 +++ 2 files changed, 4 insertions(+), 1 deletion(-)
