Sure, I can do that.  Patch for AMIC A25L{05,10,20,40,16}{T,U} and
generic AMIC is attached, as well as a pretty-printer for their status

Now here's a strange thing: The datasheets for these parts, which come
in many different versions with errata, are riddled with and omissions
and weird descriptions, probably due to quick-and-dirty copy-pasting by
whoever's writing/translating them.

A quick search of Datasheetarchive.com suggests that the following parts
A25L05P[TU] - ID 2020/2010 (T/U)
A25L10P[TU] - ID 2021/2011 (T/U)
A25L20P[TU] - ID 2022/2012 (T/U)
A25L40P[TU] - ID      2013 (Datasheet says U *and* T parts have same ID)
A25L80P     - ID      2014 (only U parts exist, AFAICT)
A25L16P[TU] - ID 2025/2015 (T/U)

I'm willing to bet that A25L40PT actually has the device ID 2023, and
*not* 2013.  So my attached patch modifies the device ID for the
A25L40PT accordingly.  I note that Erase is untested for the
A25L40P[TU]... if someone has a part with device ID 2013, I'd love to
know if its erase behavior works as expected.
