From f941c8d76c665045e5d645112a309d12523e19c7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 28 Dec 2017 13:14:16 -0700 Subject: log: Add functions to convert IDs to/from names Category and level both use an enum for their ID values. Add functions to convert these IDs to strings and vice versa. This will allow the log to output the strings instead of the (inscrutable) values. At the same time, add a new 'driver-model' category, to cover core driver-model functions and fix an incorrect value for LOGL_MAX. Tests will be added with the new 'log' subcommands.
