I guess you're asking about the IOP3xx stuff.

info as
mp<tab>
msec<tab>

gives all the details. To summarise though:

        "a" or "#alloc" - the section is allocatable
        "x" or "#execinstr" - the section is executable

"ax" seems to be what Linus uses. I used to use the long versions, but
changed to the shorter version - less characters to type, but still
fairly readable. After all, you don't catch people trying to make ls
report stuff like:

file, user read write execute, group read execute, other read execute,
2 links, owner root, group root, 44 kibytes, modified xxxx, name "foo"

(or I hope you don't! 8))
