Browse Source 
http://www.amictechnology.com/pdf/A25L20P.pdf covers:
AMIC A25L05PT
AMIC A25L05PU
AMIC A25L10PT
AMIC A25L10PU
AMIC A25L20PT
AMIC A25L20PU
http://www.amictechnology.com/pdf/A25L16P.pdf covers:
AMIC A25L16PT
AMIC A25L16PU

Clarify the situation surrounding the A25L40PT and A25L40PU chips which
share the same RDID values, despite the fact that their erase block
layouts are different.  Rudolf Marek tested and confirmed the distinct
erase block layouts of these chips.

Add a pretty-printer for the AMIC SPI chip status register
Add a generic AMIC chip type.

Corresponding to flashrom svn r1096.
