[U-Boot] [PATCH] iMX: adding parsing to hab_status command
From: Ulises Cardenas Ulises.Cardenas@freescale.com
hab_status command returns a memory dump of the hab event log. But the raw data is not human-readable. Parsing such data into readable event will help to minimize debbuging time.

hab_status command returns a memory dump of the hab event log. But the raw data is not human-readable. Parsing such data into readable event will help to minimize debbuging time.

Please remove all those if else and then make sense to review

This was a port of a external parser. And we wanted to keep a similiar structure. However, I understand your point. I think the problem that the original programmer had was the trasversal of enums with a non-increasing order. I submitted another version of it addressing the issue.
Thanks, Ulises
