+Buildman has various other command-line options. Try --help to see them.
To find out what architecture or toolchain prefix buildman will use for a build,
see the -a and -A options.
+To request that compiler warnings be promoted to errors, use -E. This passes the
+-Werror flag to the compiler. Note that the build can still produce warnings
+with -E, e.g. the migration warnings:
+
+ ===================== WARNING ======================
+ This board does not use CONFIG_DM_MMC. Please update
+ ...
+ ====================================================

When doing builds, Buildman's return code will reflect the overall result:
0 (success) No errors or warnings found
128 Errors found
- 129 Warnings found
+ 129 Warnings found (only if no -W)
+
+You can use -W to tell Buildman to return 0 (success) instead of 129 when
+warnings are found. Note that it can be useful to combine -E and -W. This means
+that all compiler warnings will produce failures (code 128) and all other
+warnings will produce success (since 129 is changed to 0).
+
+If there are both warnings and errors, errors win, so buildman returns 128.

Sometimes we don't want buildman to return failure if it seems warnings. Add a -W option to support this. If buildman detects warnings (and no errors) it will return an exit code of 0 (success). Note that the definition of 'warnings' includes the migration warnings produced by U-Boot, such as: ===================== WARNING ====================== This board does not use CONFIG_DM_MMC.
