While doing this I really wanted to add "much more" error comments but I faced another reality: often the messages are there but use pr_err/log_err which is actually silenced by default with LOGLEVEL=3, so I consider this unnecessary, as decreasing the loglevel will make these messages appear. I would have expected errors to be displayed, but I understand it makes the binaries even bigger.
This is how it works for pr_err but not for log_err: if you are not using CONFIG_LOG, all log_xxx with level less than or equal to INFO are in the binary. On the other hand, if you have CONFIG_LOG=y, log_xxx are left out based on LOG_MAX_LEVEL value, while pr_xxx are left out based on both LOGLEVEL and LOG_MAX_LEVEL too (due to the fact that pr_xxx relies on log_xxx). This is quite confusing IMO. I'm working on a proposal for a simpler and clearer unified way to log in U-Boot.
