The "arm9tdmi.c" file is more of a generic ARM9 support file:

 - update comments to say so.
 - update docs to clarify that the "arm9tdmi" command prefix
   is a misnomer.
 - bugfix some messages that wrongly assume only ARM9TDMI
   based processors use this code.

-Many ARM9-family CPUs are built around ARM9TDMI integer cores,
-or processors resembling ARM9TDMI, and can use these commands.
+ARM9-family cores are built around ARM9TDMI or ARM9E (including ARM9EJS)
+integer processors.
 Such cores include the ARM920T, ARM926EJ-S, and ARM966.
 
+For historical reasons, one command shared by these cores starts
+with the @command{arm9tdmi} prefix.
+This is true even for ARM9E based processors, which implement the
+ARMv5TE architecture instead of ARMv4T.
+
 @c 9-june-2009:  tried this on arm920t, it didn't work.
 @c no-params always lists nothing caught, and that's how it acts.
