+"""
+Test the bootstage command.
+
+It is used for checking the boot progress and timing by printing the bootstage
+report, stashes the data into memory and unstashes the data from memory.
+
+Note: This test relies on boardenv_* containing configuration values to define
+the data size, memory address, and bootstage magic address (defined in
+common/bootstage.c). Without this, bootstage stash and unstash tests will be
+automatically skipped.
+
+For example:
+env__bootstage_cmd_file = {
+    'addr': 0x200000,
+    'size': 0x1000,
+    'bootstage_magic_addr': 0xb00757a3,
+}
