That's what we call a "critical POST failure".

What you want is this commit:

8a484d2b87067bfbf83583606600486ff4b4f0a2

    The patch introduces the CRITICAL feature of POST tests. If the test
    marked as POST_CRITICAL fails then the alternative, post_critical,
    boot-command is used. If this command is not defined then U-Boot
    enters into interactive mode.

You can find this in the lwmon5 branch of the U-Boot  git  repository
where  it  is  queued up ready for merge into mainline as soon as the
next merge window opens again.

Best regards,

Wolfgang Denk
