Note that many of these tests are implemented as commands which you can
run natively on your board if desired (and enabled).

+Memory Map
+----------
+
+Sandbox has its own emulated memory starting at 0. Here are some of the things
+that are mapped into that memory:
+
+ 0 CONFIG_SYS_FDT_LOAD_ADDR Device tree
+ e000 CONFIG_BLOBLIST_ADDR Blob list
+ 10000 CONFIG_MALLOC_F_ADDR Early memory allocation
